Recently I got a good frame rate when placing thousands of lights because of your help. Now I want to extend my game to support a simple indirect illumination using reflective shadow maps. I read the paper and I found something that I don't understan... |

|
Hello everyone,
In my game I use deferred rendering. I create bounding box for each point light and then use that box by projecting in 2D and then use scissor test to draw the required area affected by the point lights. Here is the test bench:

Shadow draw order problem
|
hey, I have fully implemented Parallel split shadow map. But if an object A is over object B and the draw order is A then B then A doesn't cast shadow. However if the objects are interchanged and draw order is kept same then shadows appear. So how to... |

Confusion With Render Targets

Present Situation:
Currently I am working on deferred renderer. I applied VSM but as the world is large there was a lot of aliasing. So I switched to Paralel Split Variance Shadow Map. I am having 2 splits so the scene must be rendered 2 times... |

Strange problem

I am trying to develop VSM.
Here is the problem:

Previously I had a problem of aliasing in my shadows. I solved that problem by cropping the shadow matrices depending upon the view frustum and then this new problem. I developed my co... |

Hello,
Ok, what my problem is that I have developed deferred rendering engine for my game. Now I want to apply shadows to it. So first I am trying with simple PCF shadows. I thought rather constructing position from depth to apply shadows in the def... |

Sample Reflective shadow maps

Thanks for the reply. I am getting it somewhat clear :)
But I do have a question. When I was doing my deferred pass I was rendering my light volume geometry like spheres for point lights, cone for spotlights, etc. But in sampling RSM and calculating... |

Thanks for the reply.
I know but I was just trying to learn indirect illumination the simple way. And about LPV they go off my head because of SH stuff. I just want to know how can I sample the rsm. LPV is a long way to go. Also my game is built ... |

Sample Reflective shadow maps

I googled and found that by using vertex texture fetch I can get the position of the texel at which I should place the sphere (point light source). This is OK but now how would I iterate through all the point lights by drawing all the spheres at thei... |

Deferred rendering camera close to point light fps drop

Thanks for replying. What I did I replaced my code of scissor testing and just draw low poly spheres to a rt and guess what?? It worked like a charm. No more frame rate drops even with 2000 lights. Just a slight drop (60) when I placed all the lights... |

Thanks for the replies.
No, I am currently drawing all the lights whether visible to the camera or not. But what if 14-20 lights are all visible? They are still causing a lot of frame rate drop. What should I do iluminate an apartment hallway where... |
