$ graph1_pi
This is version 1.0 of mplot::Visual<glver=3.1 ES> running on OpenGL Version OpenGL ES 3.2 Mesa 25.2.8-0ubuntu0.24.04.1
GL error: GL_INVALID_OPERATION | /home/mikusm/Code/mathplot/mplot/VisualModel.h:360
terminate called after throwing an instance of 'std::runtime_error'
what(): GL error: GL_INVALID_OPERATION
Aborted (core dumped)
After a bit of debugging, it seems to be caused by VisualModel.h render() method which uses non ES compatible glPolygonMode().
VisualModel.h Lines 305 and 307:
// Enable/disable wireframe mode per-model on each render call
if (this->flags.test (vm_bools::wireframe)) {
_glfn->PolygonMode (GL_FRONT_AND_BACK, GL_LINE);
} else {
_glfn->PolygonMode (GL_FRONT_AND_BACK, GL_FILL);
}
VisualModel.h Line 363:
// Now render any VisualTextModels
_glfn->PolygonMode (GL_FRONT_AND_BACK, GL_FILL);
auto ti = this->texts.begin();
while (ti != this->texts.end()) { (*ti)->render(); ti++; }
Commenting these out fixes the error and renders the graph correctly. That works for my use case, but since it completely disables wireframes, things like hexgrid_pi don't render how they should.
