Apr 30	comment	Has piracy ever resulted in a developer getting shut down? I don't think this question can be answered, as it is only speculation how many of the pirated copies are actually lost sales. I am certain there are developers that could have survived with the extra sales but it is impossible to proof really.
Apr 30	answered	vertices, better to have more but draw a smaller area or less but expand a larger area
Apr 18	answered	Deferred decals normal problem
Apr 18	comment	Render just the pixel under mouse cursor in DirectX Using an off center projection matrix combined with a smaller viewport is a valid way to achive what you want and may result in a higher peformance as non-visible geometry gets clipped before the fragment shader is executed but scissor rects are far simpler to use.

Mar 6	comment	How to implement collision detection of portals? As far as I know they explain some of the stuff in the developer commentary of Portal 1.
Mar 5	comment	How to occlude lights in Unity3D? If the light volume is occluded the light may not influence any pixels on the screen. I didn't work with unity that much but it would be very strange if light volumes were excluded from occlusion culling. How do you determine that lights are not culled?
Feb 27	comment	Strange rendering in Direct3D 10 It definitely looks like a transposed projection matrix. You could debug this using PIX.
Feb 27	comment	Strange rendering in Direct3D 10 You can specify a matrix packing when compiling the effect: D3DXSHADER Flags Perhaps the default did change.
Feb 27	comment	Strange rendering in Direct3D 10 Could be the wrong matrix order, eg passing row major when the shader expects column major or vice vesa. Try if swapping the order of the operants in your mul() calls fixes this.
Feb 27	comment	How to occlude lights in Unity3D? In Unity Pro, OcclusionCulling should handle lights too.
Feb 27	comment	How to occlude lights in Unity3D? You can check if the camera frustum and the lights frustum intersect, but I expect unity is already doing this.

Jan 28	comment	How to do perspective projection “parallax” but without changing the scale or offset of objects? If I understood it correctly, your way of scaling should be fine. A position change should not be required but you have to choose the correct scaling origin, probably screen center in up/down direction and object center in left right direction, depending on your setup.
Jan 28	comment	How to do perspective projection “parallax” but without changing the scale or offset of objects? I'm still not entirely sure what the problem is. You want to know the size and position of a xy plane that fills a specific screen area for a given depth value?
