I'm writing a NURBS class that uses OpenGL's GLU extension to do rendering, but I just realized I have no idea how to set the control point weights. It's not in the Red Book or the GLU documentation, and the web doesn't mention much of it, either. Is it possible that GLU's NURBS implementation just doesn't include this feature? If so,...
I'v followed a tutorial to get the GLU tesselator working. It works except the interpolation for colors of new points causes a crash after creating a random polygon(error reading from memory...) This is my callback where it crashes: void CALLBACK combineCallback(GLdouble coords[3], GLdouble *vertex_data[4], GLfloat weight[4], ...
Using Iphone and Objective C Im trying to find what plane has been clicked/touched in my opengl view. Typically i would use glPushName/ flPopName but this function doesn't seem to be implemented in the sdk or defined in . Does anyone know where to get there useful functions or another way to get the object that was clicked? ...
I'm using GLUTess to tesselate polygons. Sometimes it crashes with a null pointer issue and I have no way of knowing why since I just link to glu32.lib . Is there a way to see the source and get the exact line it crashes on? Thanks ...
I'm using GLUTess to tesselate polygons. After several tests, I realized glu32.lib which links to glu32.dll, crashes every once in a while. Whereas GLU which I got from the opengl sdk, is solid as a rock. Unfortunately though, by not linking to the windows dll, this means I need to drag around GLU.dll with my app instead of relying on Wi...
I have found that my application crashes with a null reference exception right here in sweep.c in GLU source code: static void ConnectLeftVertex( GLUtesselator *tess, GLUvertex *vEvent ) /* * Purpose: connect a "left" vertex (one where both edges go right) * to the processed portion of the mesh. Let R be the active region * containi...
Here is my issue. I'm tesselating complex, self intersection, multicontour polygons with hundreds of verticies. The GLU Tesselator crashes with null pointer 0x0000000 issue. It never ever crashes when I do not make self intersecting polygons. If it does not intersect, it will never crash no matter what the circumstances. I check for NULL...
I'm trying to make a vector drawing application using OpenGL which will allow the user to see the result in real time. The way I have it set up is with an edge flag callback so the glu tesselator only outputs triangles which I then pass to a VBO. I'v tried t make all my algorithms as fast as possible and this is not where my issue is. Ac...
Hi, I registered a CALLBACK using: gluTessCallback(tess, GLU_TESS_COMBINE, (GLvoid(*)()) &scbCombine); Where scbCombine is a function directly in the same .cpp file: void CALLBACK scbCombine(const double newVertex[3], const double *neighborVertex[4], const float neighborWeight[4], double **outData) { instanceMDC->cbCombine(newVe...
I have MinGW and MSys set up on a windows 7 machine, but the glu libraries that came with it are old, and dont support gluBuild3DMipmaps. I have searched everywhere for a precompiled glu library for MinGW that I can use, but I can't find anything... I can't even find documentation on how to build one. So where do I get the newest versio...
