MUHAHAHAhahah....3D isnt THAT difficult!

Hey peeps.
ive been playing around with the Terrabit demo, and ive added some b3d like commands like positionentity and turnentity... and cameras..... snot that difficult y'know....

Sorry i dont have a link. But this OpenGL is realy not as killer as i first thought!

[edit]
I just hit the point where i need to do "local" transformations...

This, is, as a beginer, where i fail!!!!

...So i suppose this is where this thread becomes useful....

I have the pitch/yaw/roll values stored.

i have a local x/y/z vector to move by.

How do i apply that vector so that 0,0,1 always moves the object the way its facing?

These pages *might* provide some insight

I have a book called 3D Maths Primer for Graphic and Game Development which explains this quite well.

If you have a look at the 3D Engine demo code, (in the BlitzMax showcase) there is a fair bit more in the engine than is demonstrated by the demo.

Including local translation. MoveEntity as opposed to TranslateEntity, cameras etc. Most of it is in there.

ooOOoh.. then i shall have a look...

cheers :D

You probably need to use the stack to push and pop matrices so that you can move into local coordinates rather than global? Something like that.

im already doing that


Terrabit, youre engine is cooool... i like it! i only used the glhead demo to do mine- and so far its 100%b3d compatible...
