In Topic: RSM indirect Light flickering

06 April 2014 - 05:03 AM

But when do I do that ? My first idea was the standart way of indirect lighting with RSM : Create Vector a = reflect( Lightposition - rsm pixel position, rsm pixel normal). Now vector a is the vector which is (maybe) directed to our dest pixel. Now I do nDotL with the dest pixels normal and vector a. Now I have to multiply this float with the rsm color and divide it by the fallof. But I don't realy unterstand what you mean with the binary test. Maybe someone can give me his way of implementing that, because I thing my way is too expensive.

Oh thanks that makes sense. Well the double sided equation was my first idea of doing that. Is there an other way to do that ??


In Topic: Increase texture reading speed

Thank you very much for the answer. Your right it isn't very efficient when I use one 144 samples of a 1024*768 pixel rendered RSM...

My idea would be to store the pixellights in an array structure with position/normal/flux so I have not to sample the points every pixel n times and have only a 1D array and only one for loop ( which I think doesn't really inscrease the speed...) 

But storing the VPLs in a buffer would be more effecient I think but I have one problem with that. I don'T really know how to do that without a rendertarget...so only with a constantbuffer or any type of buffer. Is there a way to same the array of my pixellightstructure in a buffer and read it like a constant buffer in each frame ??

Okay I've got it I had to set an other depthstencilbuffer when writing the second time to the gbuffer


In Topic: HLSL project a texture to the frontside of an object

Okay thanks but what is about other objects that are behind that one ?? It should produce a kind of shadow but is that possible to check ??
