WebMar 17, 2024 · For a cylinder, you'll more often want to use a cylindrical projection: Here, the U (x) coordinate of our UV is our arc-length around the cylinder, and our V (y) coordinate is the vertical position of the vertex. You can get the arc-length value by multiplying the total angle stepped so far (in radians) by the radius of your cylinder. WebOct 24, 2014 · Here's the cylinder I have created: void drawCylinder (float r, float g, float b) { setMaterialColors (r, g, b); glColor4f (r, g, b, 1.0); /* top triangle */ double i, resolution = …
