Hi all, My team is currently limited to drawing images on an opengl 1.4 platform, which means that we can't use any nifty texture mapping to draw an image (yes, we're confined to using the intel integrated graphics platform, it's very annoying). So far, we're able to draw, scale, and flip an image, but the guy doing the graphics claim...
Hi all, Despite an earlier question (asked here), our project is constrained to using glDrawPixels, so we have to do some hackery. One of the feature requirements is to be able to have a magnified view show up on a clicked region of an image; so, looking at an image, I want to click the mouse, and have a 200% image window show up wher...
I'm writing a drawing application, and the drawing canvas is an OpenGL texture. When you draw onto the canvas, it determines which region of the canvas texture has been changed, and copies that pixel data out (using glReadPixels) before applying the changes you made. To undo, I want to simply revert to the previous texture state using t...
glDrawPixels(GLsizei width, GLsizei height, GLenum format, GLenum type, const ovid *pixels); Is there a function like this, except instead of accessing CPU memory, it accesses GPU memory? [Either a texture of a frame buffer object] ...
