openGL exercise

Wednesday, January 12th @ 2:34 pm

for my OpenGL exercise I made a little drawing tool of sorts. You can draw little line segments around the screen in 3 dimensions (arrow keys move cardinal directions, and x and z move “in” and “out” of the screen). I used a combination of key, keyup, metro, and delay to incorporate a delayed key-repeat function so you can draw by holding down the keys. You can also change the color of the line by using the q (black), w (red), e (green), and r (blue) keys. The 1-6 number keys change the line thickness from 1 to 11. If you click in the center of the screen where the line starts, the handle tool is on so you can rotate the screen in 3 dimensions to view your line drawing. The space bar resets the view to default. The \ key switches between orthographic and perspective projection (with the default set to orthographic). And lastly, the backspace/delete key erases the drawing and moves the cursor back to the center of the screen.
