dear all, I'm a beginner of directFb and I have a lot of difficulties in order to find "start documentation"... is there a reference manual or something similar?
In particular I'm able to load image and I will start to use layer and alpha channel but I would like to rotate object in 2D and 3D ( till now 2D...)... for exampel I have read in this mailing list that it is possible to rotate (90°) an image with texturetriangles but it doesn't work and in particualr I don't understand DFBvertex how it works... (what is w coordinate!??!). this is the code that I have used: >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> You can use TextureTriangles() to do that. The following code blits "src" surface to "dst" surface rotated by 90 degrees. /* BEGIN CODE */ DFBVertex v[4]; /* [x,y] are the coordinates of the destination point. */ /* [width,height] is the size of the source surface. */ v[0].x = x; v[0].y = y; v[0].z = 0; v[0].w = 1; v[0].s = 1; v[0].t = 0; v[1].x = x+width; v[1].y = y; v[1].z = 0; v[1].w = 1; v[1].s = 1; v[1].t = 1; v[2].x = x+width; v[2].y = y+height; v[2].z = 0; v[2].w = 1; v[2].s = 0; v[2].t = 1; v[3].x = x; v[3].y = y+height; v[3].z = 0; v[3].w = 1; v[3].s = 0; v[3].t = 0; dst->TextureTriangles( dst, src, v, NULL, 4, DTTF_FAN ); /* END CODE */ However this only works if TextureTriangles() is accelerated, since there is not software fallback. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> many thanks for any suggestions... claudio stagni
