OpenGL - Console application when compiled with MingW
|
Hello everyone!
How are you? I'm great. I recently defended my Bachelor of IT-Engineering
to a pretty nice grade. Now it's time to get back to business.
Therefore, I'm again putting some time into my projects at home. :)
Anyway, i just str... |

GLSL - Is there really no way to read and write in one go?
|
Hello everyone!
I was thinking, if my fragment shader writes something. Anything, really, is it not possible to use that
in an earlier stage for the next vertex?
I just want to check on the vertex stage for the next vertex, wether something... |

Searching for an efficient way to sample one of multiple textures in shader
|
Phew, long title!
Alright I would like to sample one of 8 textures, but only my shader
decides which texture to sample. I refer to the texture in the shader very often,
and thus it becomes slow to branch like this:
vec4 cola;
if(texi... |

Excess fragment operations
|
Hello everyone,
I've been searching on google -and in the forums for early z-test,
and found a lot of stuff. I'm not sure I understand it however.
I have an expensive fragment shader, and I'm feeling there's overdraw sometimes.
I think t... |

Is it possible to erase instead of drawing?
|
Hello everyone,
Yes, this is sort of a strange issue.
I am drawing sort of a mask/stencil to a framebuffer, whos texture i sample
in my fragment shader.
The fragment shader decides how to draw, or whether to draw at all, by examining
this sa... |

Best way to create VBO from std::vector?
|
Hello everyone!
I'm trying to fill vertex information into a std::vector,
and would like to create a vertex buffer object from it's contents afterwards.
As a vector also stores data in a continuous block of memory, I thought that'd be easy. I wa... |

VBO Color Problems
|
Hello everyone,
I'm trying to pack my homemade vertex struct into a VBO and send it off to be rendered.
Currently, it looks like I got the geometry right. The trouble concerns the
colours, that are a part of my struct:

Orthographic Projection and Depth issue.

Hey everybody! For my view class, I'm implementing an option to use either perspective or orthographic projection. I got my shader to write the depth
value of my raycast fragments, so that part works excellent in perspective mode.
I have a couple... |

Texture Units, Shaders and Binding?

Hello everyone.
I've been searching the forums for a matching issue,
but I'm not sure other people have been needing a so basic explanation of things.
Perhaps that means I'm dumber than those guys, I dunno. :/
Anyway, I'm just putting a few e... |

[solved] Bad fragment depth value from shader

Hey guys,
I'm having some issues with my shader. It's pretty large so I'll attempt to post only the related parts.
I have two overlapping boxes. One rendered with the default pipeline, and one rendered with my raycaster shader.
Now... |

Thanks for the help, man! It's nice to have so quick people around on GD.
Have a happy newyear CRYP7IK, right! |

OpenGL - Console application when compiled with MingW

Yeah i thought that too, i just thought maybe i was suppressing it somehow through the way i compile and link. - I got:
int main(int argc, char **argv)
, which i think should be sufficient. Note i haven't changed any of my code since i built it t... |

Following A Path...What am I missing?!?
|
Many aTan implementations return the angle in radians. Is this what you want?
Because you were talking about degrees.
Edit: nevermind, your code looks nice and generic. |

Dev-C++ doesn't work anymore

If you want to teach your friend the basics,
Scratch all IDEs and teach him

That will suffice for compiling all simple files.
The next step with headers and inclusion of object modules
Is still easy in the command line. I ag... |

DREAM act!

Give your friend a bike and help him/her get a job in his neighborhood.
That is some good help you can offer, i think! |

creating a class for rockets, should i use a static for the models mesh?
|
You don't have to declare your rockets static just to use a single mesh.
There are many ways to avoid this, but one would be your class having a reference of some sort, maybe a number or a real reference or pointer, to a mesh.
Why not create a... |

|
Yeah, I'm just trying to decrease overdraw in a call to a single vbo.
My fragment shader is slow, its a raycaster and the vbo contents approximate a surface of my volume.
The order of the vertices doesn't matter, so the next vertex may be anyone. |
