SceneMaxZdepth

SceneMaxZdepth Zdepth

Parameters:     Zdepth = The far clipping plane along the z axis

Returns: NONE

SceneMaxZdepth sets max Z depth allowed in the scene buffer. FACTS:       * The Scene Buffer can only handle positive Z depths from zero to it's SceneMaxZdepth Mini Tutorial:       This example creates a type of soft 3D scene, where it projects a set of pixels in 3d space. So pixels have z depth. The viewer then zooms in and out where pixels behind or beyond the max z depth are culled from the scene.    ; Create camera 1.   CreateCamera 1   CameraCls 1,off       ; max 3D Space  depth   ZRange=20000    ; Max Scene Depth  0 to 5000      SceneDepth=5000   SceneMaxZdepth SceneDepth+1       ; perspective projection   ProjectionX=300   ProjectionY=300    ; Depth Shading      DepthScaler#=150.0/SceneDepth             ; Start a Do/loop   Do      Cls RGB(0,0,0)          ; Tell PB to capture the following GFX commands    ; to the scene Buffer      CaptureToScene      ClsScene          ; Get the camera X & Y position      CamX=GetCameraX(1)      CamY=GetCameraY(1)          ; reset the rnd number sequence      Randomize 056          ;      For lp=0 To 5000         x     =RndRange(-2000,2000)-CamX         y     =RndRange(-2000,2000)-CamY                  z     =RndRange(1,Zrange)-CamZ         ThisRGB=RndRGB()                  If Z>-1            If Z<=SceneDEpth               CaptureDepth z                            ; shade the Colour of this pixel               ThisRGB=RGBFade(ThisRGB,Depthscaler#*(SceneDepth-Z))                            ; Draw a captured dot to the scenebuffer               DotC 400+(x*ProjectionX)/z,300+(y*ProjectionY)/z,ThisRGB                           EndIf                     EndIf      Next          ; Draw the camera      DrawCamera 1            Text 0,0,FPS()            camZ=(ZRange/2)+SinRadius(angle#,ZRange/3)      Angle#=WrapAngle(angle#,0.10)                  Sync   Loop
