An old but nice screenshot from my game engine
|
A screen I took a year ago on an engine I was making then. The screen shows features omni directional soft shadows, normal/parallax (based on LOD) mapped surface with emissive parts and some other effects like bloom etc. Hope you like the s... |

FBO bind not really binding
|
Yeah,
tiago,
you can take look at the first link I had pasted in my previous post,
I think some forum poster talks about reading the image without texture, but he does some
glPixelStore stuff. If you've got the time on your hands, you ca... |

DOF, Refraction, Particles, Compromises.

oh hmm, sort I guess and mix the depths. No other go no?
Or better yet, just design level such that funny situations like this never arise.
I guess it would make sense to just tint the glass, and make it refractive and then apply its DOF itsel... |

cgCreateProgramFromFile Failed: CG_FILE_READ_ERROR
|
Oh, hmmm.. why don't you try sending the GL context to dialog and create a new Cg context?
Or you can create another GL context in the dialogue and then create a new Cg Context, with that gl context and then switch back to your main context.

rendering 2 textures using FBO

haha, glad its now working. Happy to help. Haha yeah, thats why in the program I sent it had worked, since I was blending and not using offset. |

FBO bind not really binding

Hi tiago,
I did some research into your problem and I have found that,
glReadBuffer(GL_COLOR_ATTACHMENT0_EXT) will work properly if there is a texture bound
that FBO's color attachment.
So just try attaching a texture to that FBO's color at... |

rendering 2 textures using FBO
|
hi murderv,
You'll laugh about the problem, it was very basic mistake, you had forgotten to set drawBuffer for the second fbo, (and also you are clearing color buffer before setting color, leading to no color change for that fbo, if that is a prob... |

rendering 2 textures using FBO
|
Actually I understood that your not using MRT, was just telling the way I setup my FBO's.
You can host the program somewhere, and I'll try to fix it, but you'll have to tell me how to build it etc, I don't have any java/ogl experience.
Pretty... |

rendering 2 textures using FBO

hmm, I think your init code may be wrong,
try this method,
FIRST COLOR BUFFER
1) gen render buffer
2) bind render buffer
3) RenderbufferStorageEXT(GL_RENDERBUFFER_EXT, internalFormat, Width, Height)
4)FramebufferRenderbufferEXT(GL_FRAMEBU... |

I'll give you an example,
void vertex_program(float4 position : POSITION,
float2 texcoord: TEXCOORD0,
out float4 oPos: POSITION,
out float3 oTexcoord: TEXCOORD0)
{
oPos = mul(mvp, position);
float4 eyeP... |

What I'm saying is, you should manually output eye space distance. Kindly look at the images in my previous post. I have edited it to show that it works. If you manually output depth, even transparent objects will have true depth. |
