I work in mobile game development.

My expertise is in 3d graphics, real-time and offline rendering.

I use c++ for most of my work.

comment How do I change the material of an object with Script in Unity?
in C#: gameObject.GetComponent<MeshRenderer>().material.mainTexture = new_texture; the "Javascript" code should be similar to this.

Do you want to change the material or a property from the assigned material ?

comment Fixing/avoiding Z-fighting with decals OpenGL
it will be hard to fix the problem from glPolygonOffset. I would advise you to read on the z buffer: outerra.blogspot.ro/2012/11/…

comment SpriteKit - How to jump to specific position?
"real" physics use Newton's laws of motion and take into account gravity, mass, and other forces. "Fake" physics is just a function that you write out of your head that looks good, something like f(x) = sin( pow(x,0.5f) * Pi);. Consider having point A and B and you want to jump ObjectA from A to B => ObjectA.position = lerp(A,B,Time) + Vector.Up * f(Time) and Time is from 0 to 1. No approach is better than the other, "fake" physics can look better or worse , it all depends on your imagination

do you need real physics or fake physics ?

comment Ray-Triangle Intersection Detection using Barycentric Coordinates
it's hard to spot out of the first look the problem here , so it would really help if you can simplify the code and provide input data that is mathematically correct but the code fails to compute.

comment Specular banding with high specular power
just a guess: try float3 h = normalize( reflect(toLight,normal) );, and spec = pow(dot(v, h) * 0.5 + 0.5, specPower) * diffuse;

comment Android OpenGL ES 1.0 - Glow/Bloom effect
i would say that you can do it in GL 1.0 but i think you are better off without it since it would be very expensive on performance, hard to implement and visual quality would probably not be that great. You can do it on CPU (get framebuffer texture from video memory and work those pixels with 2 for's) or you can do it by rendering the glowing objects from scene multiple times with a small additive (from vertex color) and a small xy offset
