Hey
Drivers after Adrenalin Edition 22.5.1 have issues with glEdgeFlagPointer.
Adrenalin Edition 22.5.1 works fine.
Tested drivers from Adrenalin Edition 22.5.1 to 22.11.2
Running on RX 6800XT graphics card.
Sample code
#include <tchar.h>
#include "Source\glut\include\gl\glut.h"
GLdouble aVertices[]=
{
-0.6, -0.75, 0.5,
0.6, -0.75, 0,
0, 0.75, 0,
};
GLboolean aEdge[] =
{
GL_TRUE, GL_FALSE, GL_TRUE
};
static bool flip = false;
// Clears the current window and draws a triangle.
void display_arrays() {
// Set every pixel in the frame buffer to the current clear color.
glClear(GL_COLOR_BUFFER_BIT);
glColor3f(0, 0, 1);
glEnableClientState(GL_VERTEX_ARRAY);
glEnableClientState(GL_EDGE_FLAG_ARRAY);
glEdgeFlagPointer (0, &aEdge);
glVertexPointer (3, GL_DOUBLE , sizeof(GLdouble) * 3, &aVertices);
glDrawArrays (GL_TRIANGLES, 0, 3);
glDisableClientState(GL_EDGE_FLAG_ARRAY);
glDisableClientState(GL_VERTEX_ARRAY);
glFlush();
}
// Clears the current window and draws a triangle.
void display_Basic() {
// Set every pixel in the frame buffer to the current clear color.
glClear(GL_COLOR_BUFFER_BIT);
glColor3f(0, 1, 0);
glBegin(GL_POLYGON);
glEdgeFlag (true);
glVertex3f(-0.6, -0.75, 0.5);
glEdgeFlag (false);
glVertex3f(0.6, -0.75, 0);
glEdgeFlag (true);
glVertex3f(0, 0.75, 0);
glEnd();
// Flush drawing command buffer to make drawing happen as soon as possible.
glFlush();
}
//----
int _tmain(int argc, _TCHAR* argv[])
{
// Use a single buffered window in RGB mode (as opposed to a double-buffered
// window or color-index mode).
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
// Position window at (80,80)-(480,380) and give it a title.
glutInitWindowPosition(80, 80);
glutInitWindowSize(400, 300);
glutCreateWindow("Triangle with glEdgeFlagPointer/glEdge");
// Tell GLUT that whenever the main window needs to be repainted that it
// should call the function display().
glutDisplayFunc(display_arrays);
// glutDisplayFunc(display_Basic);
// Tell GLUT to start reading and processing events. This function
// never returns; the program only exits when the user closes the main
// window or kills the process.
glPolygonMode (GL_FRONT_AND_BACK, GL_LINE);
glutMainLoop();
}
Display display_Basic() with glEdgeFlag works fine and creates this image:
Display display_arrays() with glEdgeFlagPointer produces nothing:
Best Regard

I have tested with 23.7.1, and it is not working 😞, thanks for asking.
