Hey, I am having a problem displaying or loading a buffer with an array of vertices. I know that array works fine because I am able to render it using a loop and a glVertex command. I can't figure out what's wrong. Your insight is highly appreciated.

GLuint vboId;
 glGenBuffers( 1, &vboId );
 glBindBuffer( GL_ARRAY_BUFFER, vboId);
 glBufferData( GL_ARRAY_BUFFER, count*sizeof( GLfloat ),array,GL_STATIC_DRAW_ARB );
 glBindBuffer( GL_ARRAY_BUFFER, 0 );

 printf("%d\n",count);

 glEnableClientState( GL_VERTEX_ARRAY );
 glBindBuffer( GL_ARRAY_BUFFER, vboId );
 glVertexPointer( 3, GL_FLOAT, 0, 0 );
 glDisableClientState( GL_VERTEX_ARRAY );

 printf("vboId: [%hd]",vboId);
 glDeleteBuffers(1, &vboId);

Help?

Initializing and drawing a mesh using OpenTK

I'm implementing a "Mesh" class to use in my OpenTK game. You pass in a vertex array and an index array, and then you can call Mesh.Draw() to draw it using a shader. I've heard VBO's and VAO's are the way to go for this approach, but nowhere have I found a guide that shows how to get Data Video… >>> More

Using a framebuffer as a vertex buffer without moving the data to the CPU

as seen on Stack Overflow - Search for 'Stack Overflow'
In OpenGL, is there a way to use framebuffer data as vertex data without moving the data through the CPU? Ideally, a framebuffer object could be recast as a vertex buffer object directly on the GPU. I'd like to use the fragment shader to generate a mesh and then render that mesh. >>> More
