Is work count being calculated correctly?

[shoxsz]

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:

Fornos/Src/meshmapping.cpp

Line 165 in 75e8ec5

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

calculates the total work that the shader must do, but isn't it going to force an index out of range(which is silently suppresed in the shader)?

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.
