Hi, I have a scene graph with multiple cameras as follow :
Camera 1 : - clear mask : color and depth - use FBO_Camera_1_Color as color buffer attachment - use FBO_Camera_1_Depth as depth buffer attachment Camera 2 : - clear mask : none - use FBO_Camera_2_Color as color buffer attachment - use FBO_Camera_2_Depth as depth buffer attachment Now, I would like the "Camera 2" : - to use "FBO_Camera_1_Color" as an INPUT color buffer (do not write into this buffer, write into "FBO_Camera_2_Color") - to use "FBO_Camera_1_Depth" as an INPUT depth buffer (do not write into this buffer, write into "FBO_Camera_2_Depth") So this way : - "FBO_Camera_1_Color" and "FBO_Camera_1_Depth" remains intact even after camera 2 rendering. - everywhere the camera 2 do not write data, data from camera 1 are visible The first solution would probably to copy FBOs before camera 2 rendering : - "FBO_Camera_1_Color" into "FBO_Camera_2_Color" - "FBO_Camera_1_Depth" into "FBO_Camera_2_Depth" How to do that ? Should I use another camera and a renderquad to perform the copy, or is there any OSG functionnality to copy FBO ? Even better, is there a second solution to provide an "input" buffer attachement to a camera ? Thank you!
