As of right now I have a brief understanding of how one would do a bloom effect on a programming language centered around shaders (example: XNA) and as of now, I havent the slightest idea how one would go about doing a fast bloom in blitz3d unless they did what a shader does and look at each pixel one by one. so can anyone at least face me in the right direction of how to do this?

If you want the quick and easy way I would suggest the ASHADOW library. Its post processing effects such as Bloom, blur and depth of field are quite nice.

A method using just blitz would be to grab the screen contents via the copyrect command, and using some offsets or scaling with different blend modes to achieve a decent(but slow) effect.

Do a search. This topic has been discussed many times, and there is some demo code in the archives.

Ashadow is the best way.
