I've been experimenting with writing gpu plugins but ive had problems with
getting and setting values from a multidimensional array that I pass in to
the CU file.
This snippet in cpp demonstrates the problem that Ive had with the gpu
implementation. I get errors when I try to get, set, or do anything with
the double array. Basically, Im trying to keep cuda and maya calls
separate. Maybe this is a mistake
For example, error c2109: subscript requires array or pointer type in the
cpp file
or if the same code is run from the CU file, error: expression must have a
pointer-to-object type
const int size = 100000;
double inputMeshPts_PROXY[size][4];
inputMeshPts.get(inputMeshPts_PROXY);
int lengthPts = inputMeshPts.length();
if (useCUDA == 1)
{
double *inputMeshPts_CUDA = &inputMeshPts_PROXY[size][4];
myArray(lengthPts, inputMeshPts_CUDA);
}
MStatus abjBlendShape::myArray(int length_CUDA, float weight_CUDA, double *
inputMeshPts_CUDA)
{
for (int i = 0; i < length_CUDA; i++)
{
for (int j = 0; j < 3; j++)
{
cout << inputMeshPts_CUDA[i][j] << endl;
// inputMeshPts_CUDA[i][j] += (sculptedMeshPts_PROXY[i][j] -
inputMeshPts_CUDA[i][j]); // WHAT I WANT, EVENTUALLY
}
}
}
