basic drawing primitives on Irix

Unread postby shutitalldown » Tue Mar 20, 2018 5:06 pm

is there an example of good code which provides basic drawing routines such as lines, circles or polygons surfaces and adding a couple other useful functions for zooming images for example and doing basic image processing on byte arrays?

Do you want to create your own gimp? or use someone elses gimp... :lol:

Its quite a fun exercise creating your own editor... look up painters algorithm, alpha mixing/blending, flood fill and convolution matrices... in that order... to begin with :D

If you cba, then get an image library, there are a few, but I couldn't tell which ones available on Irix... and look up bliting and how to do it with Irix (X/Motif).

Then there's that old chestnut
OpenG...something... the name escapes me... either way its not just a 3D api.... but texturing would be useful (bitmapfonts) if you need any form of GUI and are relying entirely on an OpenG...something... context.

The recommended way is to use GLUT. GLUT is simple.
There is also GLFW, which has been ported to Irix although I don't see it packaged here.

i don't think he meant using some 3rd party stuff but actually wants to do that with irix.

so, installing the gl dev stuff should be enough to get you started. including examples.

Precisely :D

I could even use SDL, but I'd prefer learning how to use native libraries, provided by Irix >= v6.5.22.

If you want to do OpenG...something... in X, and you like dead trees... get whats known as the Green book.
