First of all, whats the purpose of this code? glHint(GL_LINE_SMOOTH_HINT, GL_NICEST); I could put there GL_DONT_CARE but it doesnt make my lines drawn, unless i use glDisable(GL_LINE_SMOOTH) So im asking if theres some built in mechanism to make it draw the lines even if the smooth lines arent supported (So it would draw them withou...
Java OpenGL line drawing with vertex buffers
Hi, I'm trying to draw many lines on the screen at the same time using OpenGL line strips and performance is slow, and it was suggested I use a vertex buffer. I'm new to vertex buffers - do I need a new one for each line I want to draw, or do I use a single buffer for all of the lines (they are not necessarily connected to each other)? A...

FLOT: How to make different colored points in same data series, connected by a line?
Hi all, I think I may have stumbled onto a limitation of Flot, but I'm not sure. I'm trying to represent a single data series over time. The items' "State" is represented on the Y-Axis (there are 5 of them), and time is on the X-Axis (items can change states over time). I want the graph to have points and lines connecting those points f...

Animate a e.Graphics.DrawLine with arrowhead
I need to "animate" an arrow. It can go in any direction (up, down, left, right and diagonals) and the arrowhead will be at the end. It needs to appear as if it is growing from orgin to the end. To make matters more complicated it has to be in a user control so it is possible to add to the controls collection in the forms and remove it t...
