HDK GU_RandomPoint::generatePoints

[tuu]

Hi everyone,

I'm very new to HDK.

Can anybody explain how to use GU_RandomPoint::generatePoints please?

I've tried to scatter points on a surface, but I don't know how to use the above method.

There is no clear information about it in the document, or maybe I didn't see it.

Thanks,

[edward]

Try the comments in GU_RandomPoint.h

Hi Edward

Thank you for reply Unfortunately, I couldn't make it works though.

It will be very appreciate if anyone can provide me some hint or snippet of code of how to use this function.

Best Regards

GA_Size num_prims;

UT_FloatArray probability;

num_prims = gdp->getNumPrimitives();

for (int i=0; i<num_prims; ++i)
    probability.append(i);

GU_RandomPoint::generatePoints(*gdp, 100, 0, probability, 0);

#include <GU/GU_Detail.h>
#include <GU/GU_RandomPoint.h>

int main()
{
GU_Detail gdp;
if (!gdp.load("box.bgeo").success())
return 1;

GU_RandomPoint grp;
UT_FloatArray prob;
prob.entries(gdp.getNumPrimitives());
prob.constant(1.0);
grp.generatePoints(gdp, 1000, 1, prob, 0);
gdp.save("points.bgeo", NULL);
return 0;
}[/CODE]

edit: ups, graham was faster.
