COLLADA: sailing the gulf of 3D digital content creation

COLLADA is a COLLAborative layout job for developing an open normal electronic Asset schema for interactive 3D purposes. This publication explains intimately how one can use the COLLADA expertise in a undertaking using 3D resources, and eventually how you can create an efficient content material construction pipeline for the main advanced improvement.

Real-Time Collision Detection

''Accurate and effective collision detection in advanced environments is without doubt one of the foundations of ultra-modern state-of-the-art laptop video games. but collision detection is notoriously tricky to enforce robustly and takes up an more and more huge fraction of compute cycles in present video game engines as more and more particular environments have gotten the norm.

Let’s have a look at the render passes panel for Blender Internal: And for Cycles: As you can see in these panels, there are many settings to be activated, but sometimes we don’t need so many for a specific render. Let’s see one by one how these passes work. The main difference between the Blender Internal render engine and Cycles is that Cycles splits the 38 B l en d er f o r V isua l Ef f ec t s Diffuse, Glossy, Transmission, and Subsurface passes into three different ones. We will see later on how to combine all these passes in the composition.

22 B l en d er f o r V isua l Ef f ec t s Now we should see something like this: That’s our plane track at its default position. We can adjust the corners in the way we need manually: Notice that now we can play back our footage and the plane should match our footage perfectly. On the right panel we can find some interesting options as well: T r ac kin g 23 By clicking on the Auto Keyframe button, we can manually adjust the corners of our plane track in case we have some problem. Another interesting option is the Image field.

Here is an example of a scene lighted by a mesh emit object only, with no additional lights: The final lighting technique we can use is IBL (image-based l­ighting). We can select a panoramic image to light up a scene in a very accurate way. It will also provide us with nice reflections. By using an HDR image, we will be able to calculate the lighting in a more accurate way as it contains more lighting information with different expositions on the same file: Make sure you check the Multiple Importance option in the World panel to speed up the rendering if you use IBL or HDR lighting: Sc ene Se t u p 31 In the robot example, I used a combination of these techniques.
