For example:
if u@attrib1 = {0.1, 0.4}, the resulting array should be [0.1, 0.4]
Here it's my attempt, with a messy but working function, and another simpler but not working function.
Do you have any idea how to refactor this code?
(I attach also the .hip file for your convenience)
void unroll_OK(int ptnum; int attrib_size; string attrib_name; float attrib_values[]) { if (attrib_size == 1) { // Single float value attrib_values[0] = point(0, attrib_name, ptnum); } else if (attrib_size == 2) { // Vector2 value vector2 val = point(0, attrib_name, ptnum); for (int i = 0; i < attrib_size; i++) { attrib_values[i] = val[i]; } } else if (attrib_size == 3) { // Vector value vector val = point(0, attrib_name, ptnum); for (int i = 0; i < attrib_size; i++) { attrib_values[i] = val[i]; } } else if (attrib_size == 4) { // Vector4 value vector4 val = point(0, attrib_name, ptnum); for (int i = 0; i < attrib_size; i++) { attrib_values[i] = val[i]; } } } // Simpler, but not working void unroll_badRefactor(int ptnum; int attrib_size; string attrib_name; float attrib_values[]) { // Use the largest vector type (vector4) and then extract the needed components vector4 val = point(0, attrib_name, ptnum); // I don't know how to dynamically cast the attrib to its the correct data type for (int i = 0; i < attrib_size; i++) { attrib_values[i] = val[i]; } } string attrib_name = "attrib1"; int attrib_size = attribsize(0, "point", attrib_name); float unroll_OK[]; unroll_OK(@ptnum, attrib_size, attrib_name, unroll_OK); f[]@unroll_OK = unroll_OK; float unroll_badRefactor[]; unroll_badRefactor(@ptnum, attrib_size, attrib_name, unroll_badRefactor); f[]@unroll_badRefactor = unroll_badRefactor;
