All GL based doom ports are able to look straight up or down.

I am trying to write OpenGL based doom/build like renderer. There is polymost source on ken silverman's site but I don't understand it. Better said i know to describe by words how it works butnot mathematically,plus there is flaw in that thing that you are not able to look straight up or down in tha...

Than you very much I have tried several things myself :) but I will look into this as soon as I will get to my rig ;). Right now I haven't much time.

Hi I need help with 2D function which takes ray as direction vector (2 floats in a type) and segment (defined as two vectors) and returns >0 when segment is behind the line (negative normal) 0 when it croses line and >0 when it is in fron of line. Or something like that, can any math geek here help ...

Hi I would like to ask whether it is possible to draw with integrated gfxlib into invisible buffer using fb drawing commands and then to blit this buffer into the win32 window?

Icon Sushi is da best ;). Frankly at least you can normally import alpha channel. I think that in explorer, shell windows and in title bar no matterwhat the icon symbolic name is, first icon in exe file is used. That means first icon in rc script. You can use API to change icon at runtime however.

About convex hull, like how to construct ones, how to slice them by line, how to collide them, sweep them. Maybe even tute how to split heavy complex polygon with holes into convex parts would be cool. I know that in libraries there are books like that but, first the math equations in such books sim...

Is there somewhere some good comprehensible resource about 2D math, like getting normal from the line, constructing bounding rectangles, convex hull, distance of point from line, angle calculation etc...?

In case of unreal mode your program is smaller because it doesn't need 50 kb DPMI server that's all.

That sounds simply awesome ;), if i understand it correctly then there should be no problem when intermixing C and FB, is that right?

Will this superradical change make possible things like linking with Qt, wxWidgets or other c++ libs? That would be real kick!

OK. There IS an unreal mode (A BUG of the CPU ???). I can use some 32 bit instructions in the real mode and use the unreal one to access all (??? up to 4 GB ?) memory. But the executable remains limited to the conventinal memory (<cca 500 KB) and affected by the 64 KB BUG. Nevertheless: FreeBASIC D...

Wouldn't this merger with GCC be disatvantage? Right now fb is quite small but later it may become bloated. As GCC is :).

May I ask which one project is FB? I guess that 60K LOC one.

May I ask in what status is GCC ABI migration right now?
