Sketch. Up 3. D Rendering Tutorials by Sketch. Up. Artists. By Majid Yeganegi. Hi every one! I embarked on this project to show my appreciation and respect to the Kerkythea team, who have had a great impact on my insight into easy high- quality rendering.
I hope you too will find Kerkythea easy to use and as fun as I did. This is an updated and revised version of a tutorial I posted over at the KT forums. There are a few points that I need to mention first before you start to learn KT using this tutorial.
SketchUp is 3D modeling software that's easy to learn and incredibly fun to use. Download SketchUp today for free and get started drawing in 3D. 2015 Dibac for SketchUp is a plugin for architectural drawing. It’s a great tool for architects and for anyone who wants to draw architectural plans using 2D tools. SU Podium section tools is included in the 64 bit version of SU Podium V2.5 for SketchUp 2015/ 2016 64 bit. You do not need to install this if you are using V2.5.x.
First of all, because this is an easy- to- use and simplified tutorial and also an architect- oriented guide, I have ignored some intricate technical material tips. Maybe in the future you will be so impressed by KT that it will encourage you to learn KT deeper. I have done another follow- up tutorial called Kerkythea – take a deeper look at materials.
It is based on more accurate material making, which may be worth looking at once you have gone through this one. One thing for sure, if you are interested in making true materials, you need to know about them, so that tutorial will come in handy. In the mean time at this early stage don’t worry about the advanced stuff, you can ignore it and enjoy simple material making.
Also, there is a little known fact about KT that by knowing and using some simple material, light, render settings with a few simple tips, you will almost certainly start creating great photo- realistic renders. Please note that this is a Sketch. Up based tutorial. On other 3d software it may vary somewhat. A PDF of this tutorial is also available for download in our Download Section.

Up – Export. Ok, let’s get started; first of all, be sure that you have installed the latest version of Kerkythea, and appropriate exporter for exporting your model to Kerkythea. Just ask at the Forum if you have any problems.
I strongly recommend you to use this installer because it is the easiest to install. If all is successful you should have a new toolbar called SU2. KT like the one shown below. Kerkythea Toolbar. If you don’t see this tool set in Sketch.
Up go to View> Toolbars> SU2. Kerkythea and ensure that you have selected and activated this menu. I will only describe the ones we are concerned with at the moment and these are the first, fourth and fifth icon. They are: “Export to Kerkythea”, “Point Light” and “Spot Light”. After you have completed your modeling and texturing in Sketch. Up it is now time to place your lights and then export your model to Kerkythea.
Generally we have two kinds of light, a Point Light and a Spotlight.A typical example of a point light would be a general tungsten light bulb and if you put it inside a shade, then that would be a typical example of spot light in general.Spotlight and Point Light. Ensayo Cuentos Chinos Andres Oppenheimer Pdf .
Now lets use point/spot lights. The icon that looks a bit like the planet Saturn, is the point light while the cone shaped icon is the spotlight.
Choose a point light, click where you want your light to be placed, and click somewhere in your model that shows the range of your light. A dialogue box will appear that lets you to rename and modify your light’s power. If you use spotlights, the second point shows the light’s target. Easy?…. yes that’s all there is to it! Spotlight Dialogue Box. After placing all of your lights now it’s time to send your model to Kerkythea to be rendered. Be sure that nothing is selected because if you have something selected, a dialogue box will ask you do you want to export selection only?
We want to export whole model so make sure you have nothing selected. So now click the export button, the first icon in the Kerkythea Toolbar. Now you can answer dialogue box with yes/no ( you can change nothing so just click OK). Maybe you are interested in a clay render that makes your render something like Maquette. If so, then the third question asked “export clay model?” must be answered by “yes”. This is a sample of clay render: Clay Render. If you happen to select this, then none of your textures will be exported to Kerkythea, and your entire model will have one material (but every object is selectable separately so that you can modify it, and if you haven’t textured your model then Kerkythea will not let you modify each object separately). TIP: As Kerkythea is physically correct, so you must pay attention to your model scale and try avoid off- scale models!!!
When your model is opened in Kerkythea at first it’s a bit confusing because of lots of gray lines you see!!! Press “V” on your keyboard.
Now it’s better to understand…. Graphical User Interface (GUI)Being more familiar with the Kerkythea interface maybe is the next step we need to quickly look at. You will find these major parts: Common Bits. Actual Kerkythea Workspace/Interface Materials. Now we are going to learn about the materials, adjusting them simply and then we can start our architectural rendering job. You can download the files you need for this here. Using “Ctrl+O” open “mat scene 2.
Hit the “Esc” and “Space” on keyboard to ensure nothing is selected and you are ready to select objects in your scene. Hit “V” to see your model with textures/colors. Now double click on @material@ the wood- textured object will be selected. As you see the selected wooden object is wrapped in a yellow mesh and in the “Scene tree view”. A tiny yellow star has appeared beside the material’s name and shows that it is now selected. Press “Alt+m” for the material editor to appear. Select Material. Kerkythea material editor can be a bit confusing but in fact very simple and handy.
There are a few elements within the material editor we need to look at first and I will go over the most common ones: Material Editor[Matte/Phong], Reflectance, Transmittance, Self Luminance, Bump Mapping and Clip Mapping are most used and common parts. Trust me, understanding just these parts will end in acceptable renders. Now what do these names mean? Most materials we see reflect the light that hits them. The “Reflectance” part of the Material Editor lets you fine tune this property of materials.
Some materials like glass, camera lenses and water, let light transmit through them so the “Transmittance” part is about this characteristic. You have seen that a candle, neon tubes, safety match or fire and also your computer monitor glow when it’s dark. Self Luminance” is about glowing emitter materials such as above. There are lots of materials that when you touch them you will find that they have scratches, grooves and small dents, or small bumps like raw fabrics. This is very hard to model.
You can achieve this type of relief using a bump map. Another difficult thing to model would be something with lots of tiny holes and very pitted, like a wooden fence. It would not be wise trying to model this kind of relief. Using a map that masks some part of the material can make it easier to create this kind of effect. This is where the Clip Mapping part comes into play. Common material features are: Reflecting – like a wood material. Transmitting – like glass.
Emitting Light – like neon bulbs or fire. Bump and Clip Maps. Material Features. Reflection and Shininess. Our wood material has a texture, and its thumbnail is shown as a brown square in front of the “Diffuse” word. Generally we call these colors or textures as “map”. By right- clicking on the actual word “Diffuse” you can change it.
First colored circle lets you to add color, second checkered square lets adding or change the material texture, the third one is for procedural textures and finally the red multiply sign is to delete color or texture or any other “map”. It is the same for other items like “ambient” “Specular” “Shininess Map” etc. Note that each time you add any map such as color, texture, etc. Note that if you are adding more than one map at the same time (at this stage I strongly recommend you to avoid!
And if you have done you can delete it by right clicking) whole weights sum must not exceed more than 0. Our material is too matt and dull and needs a bit of polish in my view. To do this add a weight color (white for example) to “Specular” item and tick the “Specular Sampling” box at the same time to have some reflectance on your material. By adjusting and increasing the “Shininess” item, you can have a polished wood while by decreasing it your wood goes more matt. Change “Shininess” to 5. Greater number end up as a clear reflect.
How to Change Your Voice to Sound More Confident. We all know that being seen as confident, but not cocky, at work can have a positive effect on our careers. From one- on- one meeting with your boss to giving a presentation to the whole team, your voice is one of the most important parts of project confidence. Here’s how to adjust your voice so that how you say something has as much impact as what you say: Evaluate Areas to Work On. You may not need to work on all of the following issues, but thinking about each area and how you measure up gives you concrete things to work on.
If you have trouble evaluating your own voice or way of speaking, ask a friend or trusted colleague to help, or record yourself speaking to get a more objective sense of your own habits. Tone: The way you say something often has an impact on what people actually hear. Two of the most common examples are vocal fry (here’s a video example from the BBC) and up- speak, or using a higher pitch at the end of sentences similar to the tone used when asking a question. Not coincidentally, both of these traits that are thought to undermine credibility are commonly associated with female voices.) Speaking Cadence: If you speak very quickly or without many pauses, it can come across as nervousness. Try these exercises to help you have more deliberate articulation. Volume: Speaking too softly or too loudly does not project confidence.
You want to aim for a volume slightly above your normal speaking level so that you’re clearly heard without coming off as abrasive. Filler words: “Um”, “ah”, and “like” are all common filler words that keep what you’re saying from flowing smoothly. Try these exercises from a professional public speaking coach to cut down on your own filler words. Vocal tics: The area you may need the most help from a friend in analyzing is common phrases or vocal tics you have. Maybe you use the same phrase when you’re buying time to think, like, “That’s a great question..” Or you could be undermining yourself with phrases like, “Sorry to interrupt..” or “I’m not sure if this matters, but..”Toastmasters has a great PDF guide and Six Minutes lays out breathing and vocal exercises you can do to generally improve your vocal presence. For example, to work on your resonance: Raise your volume a bit and say “Mmmmmmmmy name is…” Repeat this ten times up and down your vocal range.
Once you know where you need to improve, get to work building new habits by practicing as much as possible. Practice New Habits. Changing the way you speak is difficult, but the more you practice, the easier it will be for you to build new habits. After a while, projecting confidence should become second nature. Since you might not have presentations or other opportunities to practice often, here are some other situations where you can test out your new techniques: Chatting with colleagues: While you don’t necessarily need to project a ton of confidence around the water cooler, small talk with coworkers gives you a low stakes situation in which to practice. Sharing your ideas during meetings: Having your ideas heard and respected can be influenced by how confident you sound while laying them out. Next time you share an idea, focus on at least one of the areas you want to improve.
Giving feedback: When giving feedback about someone else’s work or skills, make a conscious effort to practice for at least one of the areas you want to improve on. Eventually, you want to get to the point where your confident tone positively impacts how seriously your feedback is taken. Asking questions: Whether at a meeting, during a training, or at a networking event, this is a very quick way to practice your vocal confidence. I love explaining things to small groups of people and through writing on the web, but when it…Read more Read. Consider Other Confidence Boosters. Beyond your voice, you can work on other things to present yourself as confident and come across better at work. Take up space: Stand with your feet hip or shoulder width apart, keep your spine straight (but not frozen, you’re not a robot), and try to use arm and hand gestures as you naturally would when talking.
Improve eye contact: When speaking to a group, make eye contact with different people in the audience for about 3- 5 seconds each. In a one- on- one situation, it’s okay to glance away and then make eye contact again if you feel things getting awkward. Use open body language: Don’t cross your arms, stuff your hands into your pockets, or cross your legs. Keeping your body relaxed and open makes you look at ease and confident. It’s not easy to change your behavior, including the way you speak, so be patient with yourself and try to put into practice your new habits as frequently as you can.
