What do you use for prototyping 3D games?
|
For prototyping, I'd totally recommend unity3d it does everything you asked for is free and cross platform.
I used unity3d at work for prototyping a number of games, it is more than good enough to make a full commercial title games, but we have o... |

[DirectX 10] Multiple ligths

The method you suggested originally is still a feasible idea, just because you want multiple lights doesn't mean you have to use a deferred renderer, the other person said for 5 lights you would have to render a mesh 5 times that's not true at all, y... |

Return value from Shader

I've done a similar method to how you describe before, I rendered depth into a render target, locked the texture (this was d3d9) and read the texture at the current mouse coordinate from the mouse x,z and depth you can reconstruct your world space po... |

Return value from Shader

If you have a DX11 card you could use direct compute to do your GPU calculation as this is what it was designed for.
You could issue hardware occlusion queries like the histogram average luminance method used in HDR rendering. Some clever work wit... |

[HLSL] Weird dark areas w/ simple diffuse light (screenshots included)

Number of ways you could do it, make another matrix CPU side, that is the same as matWorld but without scale and translation so only applying any rotations when u make the matrix.
If you make the translation portion of the matrix (0,0,0) the... |

If your multiplying with "matWorld" does that contain translation? you should only multiply a normal by the upper 3x3 portion of a matrix so it is only affected by rotation. |
