Now, among other things I need to know what sort of transform I need to use to create the desired effect from this math. I've tried with gfx_blit and I can get panning to work but that's all, no bending or windowing of the image. I know I'm way out of my depth with all this but I'm wanting to see it done. Code: ```//@param1:FoV 'view' 150 15 320 150 1 //@param2:eye 'eye' 1 0 1.5 0.5 0.01 //@param3:pan 'pan' 0 -180 180 0.5 1 //@param4:vsh 'shape' 0 -1 1 0 0.01 img1 = 0; img2 = input_ismaster(); input_info(src,W,H); pi = 3.14159265; //angular scale factors Sppr = W / (2*pi); //source pixels/radian d = eye + 1; wfov = pi * min( FoV, 160 * d ) / 180; //radians Drpp = 2*d*tan(wfov/(2*d)) / W; W > 0 ? ( gfx_a = W; //destination coordinates in radians xr = x * Drpp; yr = (y - Y * vsh) * Drpp; //project from dest to source azi = d * atan2( xr, d); alt = atan2( yr * (eye + cos(azi)), d ); //source coordinates in pixels sx = Sppr*azi; sy = Sppr*alt; //pan & interpolate sx = sx + W*pan/360; gfx_blit(img1, paspect, sx|0, sy|0, W, H); ); //if sx > X then sx = sx - W end; //if sx < -X then sx = sx + W end; //in(xy:[sx, sy])``` The basic desire is to have Panini type viewer for equirectangular panoramic video. __________________ mymusic - http://music.darylpierce.com mywork - http://production.darylpierce.com Last edited by plush2; 06-16-2016 at 01:40 PM.
