It seems that we can't use FI_TRANGLELIST ( from FastImage ) It just renders nothing Include "D:\Program Files\Blitz3D\bbSDK\INC\FastImage.bb" Graphics3D 800, 600, 0, 2 InitDraw Camera = CreateCamera() ;MyPoly = CreatePoly ( FI_NOWRAP, FI_TRIANGLELIST ) MyPoly = CreatePoly ( FI_NOWRAP, FI_TRIANGLESTRIP ) PolyPushPoint ( MyPoly, 100,100, $FFFF0000, 0,0 ) PolyPushPoint ( MyPoly, 700,100, $2000FF00, 1,0 ) PolyPushPoint ( MyPoly, 400,500, $200000FF, .5,1 ) PolyPushPoint ( MyPoly, 700,100, $20FFFFFF, 0,0 ) PolyPushPoint ( MyPoly, 100,100, $20FFFFFF, 1,0 ) PolyPushPoint ( MyPoly, 400,500, $20FFFFFF, .5,1 ) Function CreatePoly(WrapStyle%, TriStyle%) Local Poly = CreateBank ( 20 ) ; start with no vertices PokeInt ( Poly, 00, 0 ) ; Set Wrap Style PokeInt ( Poly, 04, WrapStyle ) ; Set the Triangle render style PokeInt ( Poly, 08, TriStyle ) Return Poly End Function Function FreePoly ( Poly% ) FreeBank Poly Return 0 End Function Function PolyAddPoint(poly, id%, x#,y#, c%, u#=0.0, v#=0.0) Local size = BankSize(poly) If size<20+20*id Then ResizeBank(poly, 20+20*id) If PeekInt(poly,0)<id+1 Then PokeInt(poly,0,id+1) Local f=20+20*id PokeFloat (poly, f+00, x) PokeFloat (poly, f+04, y) PokeInt (poly, f+08, c) PokeFloat (poly, f+12, u) PokeFloat (poly, f+16, v) End Function Function PolyPushPoint(poly, x#,y#, c%, u#=0.0, v#=0.0) Local id=PeekInt(poly,0) PokeInt(poly,0,id+1) ResizeBank (poly, 20*(id+2)) Local f=20+20*id PokeFloat (poly, f+00, x) PokeFloat (poly, f+04, y) PokeInt (poly, f+08, c) PokeFloat (poly, f+12, u) PokeFloat (poly, f+16, v) End Function While Not KeyHit (1) RenderWorld StartDraw SetBlend FI_ALPHABLEND SetAlpha 1.0 drawpoly 50,50, MyPoly EndDraw Flip Wend FreePoly MyPoly DeinitDraw End Try this ( change FastImage include ) Run the code, then modify to MyPoly = CreatePoly ( FI_NOWRAP, FI_TRIANGLELIST ) ;MyPoly = CreatePoly ( FI_NOWRAP, FI_TRIANGLESTRIP ) and run again vertices are declared, and the vertexcount is ( in theory ) good ... but nothing happend |
