Im working with open3d and I want to edit a part of the code where the increase/decrease pointsize happens.
What i am trying to do is increase/decrease the point size in a small number (like 0.01) but when I change the pointsize, the points on the screen wont change shape until the number is going over a certain number x.5 for me( like in 0.51 to 1.49 the point doesnt change and in 1.5 it is)
does anyone ever have this issue and know a workaround?
this is a part of the code that i changed in order to check if the pointsize change:
static float number = 0;
bool SimpleShaderForPointCloud::PrepareRendering(
const geometry::Geometry &geometry,
const RenderOption &option,
const ViewControl &view) {
if (geometry.GetGeometryType() !=
geometry::Geometry::GeometryType::PointCloud) {
PrintShaderWarning("Rendering type is not geometry::PointCloud.");
return false;
}
number+=0.01;
glPointSize(number);
printf("number: %f\n", number);
return true;
}
