Line thickness opengl
Nettet22. jul. 2004 · A thick line can be easily implemented by creating a tri-strip along the path, where every pair of points (one “above” the line, one “below”) is displaced by +/- a displacement vector, defined as the line segment’s perpendicular vector, normalized, and scaled to 1/2 the desired thickness of your line. In 2D, perpendicular is simple. Nettet29. jul. 2009 · With OpenGL, you can specify lines with different widths and lines that are stippled in various ways—dotted, dashed, drawn with alternating dots and dashes, and so on. Wide Lines. void glLineWidth(GLfloat width); Sets the width, in pixels, for rendered lines; width must be greater than 0.0 and by default is 1.0.

NettetHow to Draw Thick Mesh Lines. Tom Goddard August 13, 2024 Modern OpenGL core profiles don't offer line widths except for 1 pixel. On retina or high-dots-per-inch 4K displays these lines are very thin and faint and two pixel width lines would be better. Here I looked at a few ideas to provide mesh lines greater than 1 pixel wide. NettetVariable thickness Lines are most certainly among the most important components in scientific visualization. They can be used to represents axis, frames, plots, error bars, contours, grids, etc. Lines and segments are among the most simple geometrical objects.
