3D Walkthroughs (arounds)

I've been using Blitz2D for some time, but had questions about a possible use for Blitz3D. I'm using SketchUp for modeling and wanted to know about how to create walkthroughs using Blitz3D. SketchUp will output to OBJ or 3DS. I'm assuming I would want to pull those files into Giles and create a B3D file for Blitz3D. But what programming on Blitz3D is required to create a simple walkthrough (e.g. no weapons, etc.)

Thanks!

Not much really. Just a bit of collision code and FP controls.

Another FPS example. (click on the link under Code Samples on the left)

a very few lines compared to eg C++. From the top of my head:

graphics3d 800,600,32,2
setbuffer backbuffer()

player=createpivot()
camera=createcamera(player)
translateentity camera,0,1.8,0
entitytype player,1
entityradius player,0.25,0.9
translateentity player,0,10,0 ; make sure to be above he ground

land=loadmesh("land.3ds")
entitytype land,2

light=createlight()
rotateentity light,45,45,45

collisions 1,2,2,2
shoe#=1.0
while keydown(1)=0
 mxs#=-mousexspeed()/4.0
 mys#=mouseyspeed()/4.0
 movemouse graphicswidth()/2,graphicsheight()/2
 if keydown(200)=1 then moveentity player,0,0,shoe# 
 if keydown(208)=1 then moveentity player,0,0,-shoe# 
 turnentity player,0,mxs,0
 turnentity camera,mys,0,0
 translateentity player,0,-.1,0 ; gravity
 updateworld()
 renderworld()
 flip
wend

I hope there ain't too much typos. currently I cannot test it since this web-terminal has no 3D.
