Hi, recently, while investigating possibility to solve one of our internal rendering problem I got a look at
dimetric and trimetric projections ( see set of links ) http://www.significant-bits.com/a-laymans-guide-to-projection-in-videogames http://www.gamedev.net/reference/articles/article1269.asp<http://www.gamedev.net/reference/articles/article1269.asp#NEN2536> http://www.compuphase.com/axometr.htm http://www.ul.ie/~rynnet/keanea/dimetric.htm I did not find a way to change projection matrix from python, and because I'm relatively new to code, I just changed added to wmOrtho my custom function ( which was used in place of wmOrtho in couple of places) like void wmOrthoCustom(float x1, float x2, float y1, float y2, float n, float f,float scalex,float scaley,float scalez) { float l=x1/*x1*/, r=x2, b=y1, t=y2/*y1*/ , f_=f/*f*/ , n_=n/*n*/; //n - ear f - far r - right glMatrixMode(GL_PROJECTION); glLoadIdentity(); orig_projmat[0]=scalex*(2./(r-l)); orig_projmat[4]=0; orig_projmat[8] =0; orig_projmat[12]=-(r+l)/(r-l); orig_projmat[1]=0; orig_projmat[5]=scaley*2/(t-b); orig_projmat[9] =0; orig_projmat[13]=-(t+b)/(t-b); orig_projmat[2]=0; orig_projmat[6]=0; orig_projmat[10]=scalez*(-2/(f-n)); orig_projmat[14]=-(f+n)/(f-n); orig_projmat[3]=0; orig_projmat[7]=0; orig_projmat[11]=0; orig_projmat[15]=1; glLoadMatrixf(orig_projmat); glMatrixMode(GL_MODELVIEW); } where scales vars I added as members of Camera and exported to python, which allowed me to change relations between axes in object view window. Now - if Projection matrix could be exported python ( and also used in rendering pipeline, not only preview ), this might be a good feature at least at blendernation someone got interested while I was asking question. It is not just very difficult - just instead of glOrtho or glPerspective to use glLoadMatrix ( and respective function in render pipeline), but adds some flexibility. Now I do not need a feature, so have less motivation to make a complete a patch, but still decided to share idea.
