I was looking for a tutorial on creating cubemap images with some software, Blender for example

comment How to calculate reflection vector from point sprite sphere?
I am just learning about point-sprites and OpenGL in general. Even if we can cheat with the point-sprite spheres, how should I do it to account for the perspective projection? Do you know a good source that walk you through this?

So the position in the surface is sphereOrigin + N * sphereRadius? The sphereOrigin is the vertex that is the input in the vertex shader?

comment How do engines like Unreal relate to OpenGL or D3D?
@JaakkoLipsanen yes I see now, DirectX is a complete framework for game development (3d, audio, video, etc) and Direct3D is just the graphics module.

comment Rendering (rasterization / ray tracing / others)
Yey ! Thanks a lot ! This answer is straight to the point. I get it now ! I understand many things. Indeed I made my Bachelor's thesis on CUDA and then I thought using that technology on graphics and games and that's why I was searching info and there is lot of work about CUDA and rendering. Thanks again!

Ok, thanks for clearing that out. Now, is it possible to implement a ray tracing algorithm while using OpenGL? I ask this because of the Unreal Engine and CryEngine, I read they use ray tracing as render algorithm but also they are built over OpenGL (for non-microsoft platforms).

Ok got it. But how does OpenGL render lines, circles? What technique does it use?

There's an accent missing "Et voilà" haha just joking. Thanks very much I think I was thinking right but wasn't sure so I decided to ask. Thanks a lot!

Where does the physics enter? It's like I should write a physics algorithm, for instance collision algorithm and then making some circles created on OpenGL behave according to my physics algorithm?

Here's part of the answer but it just bring other questions. scientificninja.com/blog/write-games-not-engines
