template class template constructors
|
The code pretty much explains itself. How do I call a value templated class template constructor?
template<class T>
class TClass {
public:
template<int S>
explicit TClass(T foo): foo(foo) {}
private:
T foo;
};
int m... |

texture corruption?
|
I'm experimenting with tessellation shaders in OpenGL 4.0, and am trying to get a vectorfield terrain working.
I'm suffering from a problem with my offset and normal textures, but only with the x coordinate on larger textures. It's curre... |

glGetFramebufferAttachmentParameteriv

Since GL_RED_BITS etc. are deprecated in 3.x, and these are what're currently used in the SDL_GL_GetAttribute() functions, I'm looking for an alternative for querying the default framebuffer.
glGetFramebufferAttachmentParameteriv appears to do wha... |

boost::signal and copy constructor call

I'm confused as to why this code doesn't compile:

template<class T>
struct behaviour {
explicit behaviour(T& t):
t(t) {}
boost::signals2::signal<void ()> sig; // <--
private:

C++ base member access control

Just curious as to why this doesn't compile (Visual Studio 2008):

};
struct Derived : Base {

template<class T>
void func(T const& p) {
Base::func(20);
}

Visual Studio 2008 settings + Windows 7

I'm having issues with the VC++ Directories settings and Windows 7.
Firstly, the include / library directories etc. seemed to get corrupted somehow, so I reset them, and am attempting to import my settings. Everything other than the "VC++ director... |

SDL + GLEW + video resize
|
A couple of basic questions:
1. Do I have to call glewInit a second time after calling SDL_SetVideoMode to resize my window?
2. Will bad things happen if I call glDeleteTextures in the new context with the old ids when there are no textures? th... |

typedef char FAR charf

I realise this is a basic question, but what does typedef char FAR charf; typedef int FAR intf; //... actually mean. FAR is simply #define FAR.
(This is in zconf.h from zlib...) |

shaders and uniforms

Noobish shader question I'm afraid, but I've not seen anything explicit as to the correct way of doing things.
Should I be:
a) creating one instance of a shader for each object that uses the shader type, and leaving the uniforms set for that... |

Setting up G3D with Code::Blocks [solved]

Just wondering if anyone's done this successfully and can offer any tips...
I compiled G3D and GL3D myself, adapting the devcpp instructions to code::blocks, and that went fine, giving me libGLG3D.a and libG3D.a.
Using a simple g3d test applica... |

multiple geometry shaders
|
Using the Realtech extensions viewer, it appears that you need a DirectX 11 card for ARB_shader_subroutine (i.e. NVidia 400 series or ATI 5700 series upwards).
Edit: Although I'm not convinced that their database is necessarily accurate. |

Fighting the (glDraw)Elements

You don't appear to be setting up a projection matrix at all (as Erik's already said). |

multiple geometry shaders
|
I suggest linking 3 programs once, rather than relinking every frame.
I doubt the overhead is much (if at all) greater than switching between 3 programs consisting of vertex / fragment shaders only (i.e. negligible).
From the glsl 400... |

pre-text int main(int, char*[]) {}
post-text
I think this is about as small as it gets (all on one line) - note that editing sometimes seems to insert extra line breaks in it. |

Personally I'd suggest the best method of "fixing" it would be to add a nice LOD system to your terrain renderer, so that the number of triang... |

Well, if the original file size is less than 2^32 (512 megabytes if that's 2^32 bits) then the original file size is equal to the original file size modulo 2^32.

Geometry shader, point sprites to spheres
|
A few comments / suggestions:
You're outputting a varying "coord" which isn't picked up at all by the fragment shader.
The calculation of the last positions in the geometry shader is bizarre - what is this meant to do? Also, I'm not sure how ma... |
