Hi I am writing 3D modeling app and I want to speed up rendering in OpenGL. Currently I use glBegin/glEnd which is really slow and deprecated way. I need to draw very fast flat shaded models. I generate normals on CPU every single frame. This is very ...

That does mean normal and vertex array, indexed drawing cannot be used because I want flat shading (similar.
One normal per triangle just set the same normal for each vertex in the triangle.

I have 4 sets of values: y1 , y2 , y3 , y4 and one set x . The y values are of different ranges, and I need to plot them as separate curves with separate sets of values on the y-axis.
To put it simple, I need 3 y-axes with different values (scales) for...

Hello,
I'm trying to read 3D models which were created for a DirectX applications, which are defined in the following way :
In the file header, the Flexible Vertex Format (FVF) of the mesh is given (actually, I have any combinations of D3DFVF_{XYZ,DIFFUSE...

Struct EitherVertex { float x, y, z; DWORD col; float nx refers to an entire vertex struct and not just a 3 element vector)
Of your 2 options a lot depends.
Well you should be defining it as follows.

Hey math geeks, I've got a problem that's been stumping me for a while now. It's for a personal project.
I've got three dots: red, green, and blue. They're positioned on a cardboard slip such that the red dot is in the lower left (0,0), the blue dot is...

As vectors from the origin, an equation for a normal vector would be
n = ( p 2 - p 1 )x( p 3 - p 1 )

p 3 = green (upper-left) dot
Hi mattbasta,
right, the normal vector does not change by distance after in terms....

Using File::stat we can get the ctime of a given file. My question is how to change the ctime , which means the inode change time in seconds since the epoch, to a normal time representation like "2009-08-26 17:28:28". Is there any build-in or module can...
