caosdoar / fornos Goto Github PK

Hello, maybe i'm confusing something, but i was reading Fornos code and i think i have found a little problem:

This line of code:

Here for example:

uint gid = gl_GlobalInvocationID.x + workOffset;
if (gid >= workCount) return;
Pix pix = pixels[gid];

But the size of pixels is less than workCount:

workCount = ((map->positions.size() + k_groupSize - 1) / k_groupSize) * k_groupSize;
sixeOfPixels = map->positions.size();

So if map->positions.size() is not a multiple of k_groupSize, then in some point there will be an index out of range because this: if (gid >= workCount) return; will not be evaluated while gid >= sizeOfPixels is true.

The application closes when I press the Bake button, without any message. I have Windows 8.1 and AMD Radeon graphics card in Intel Core 7. On Intel 4000 graphics card also does not run.

One idea would be to include vertex color to capture meshes with colors, Meshlab saves .obj files with colors.

There does exist a flavour of Wavefront's *.obj that facilitates Vertex Coloring.. I know of two applications that can export these namely "MeshLab" (free) and "MeshMixer" (also free from Autodesk).. The vertex colours is actually found just after each vertex definition as shown below..

(Piece of *.obj)
