Hi, I’m trying to apply a 2D filter on a game which is running in 2 different viewports, using this script to split the screen:
import Rasterizer
import bge
#*******************************
def main():
controller = bge.logic.getCurrentController()
object = controller.owner
scene = bge.logic.getCurrentScene()
width = Rasterizer.getWindowWidth()
height = Rasterizer.getWindowHeight()
cam1 = scene.objects["Camera_1"]
cam2 = scene.objects["Camera_2"]
scene.active_camera = cam1
left1 = 0
right1 = width
bottom1 = int(height / 2)
top1 = height
left2 = 0
right2 = width
bottom2 = 0
top2 = int(height / 2)
cam1.setViewport(left1, bottom1, right1, top1)
cam1.useViewport = True
cam2.setViewport(left2, bottom2, right2, top2)
cam2.useViewport = True
#*******************************
main()
I’m using this greyscale filter written in GLSL (I attached a ‘Custom Filter’ actuator to an ‘And’ controller to an ‘Always’ sensor in an empty mesh’s logic bricks).
uniform sampler2D bgl_RenderedTexture;
void main(void)
{
vec4 color = texture2D(bgl_RenderedTexture, gl_TexCoord[0].st);
float fAvg = (color.r + color.g + color.b) / 3.0;
gl_FragColor = vec4(fAvg, fAvg, fAvg, 1);
}
My problem is that when I run the game the filter is applied and works perfectly only on one of the camera viewports (Camera_2), but not on the other. Is there any way I can apply the filter on BOTH viewports?
PS: I’ve also tried running the filter from Camera_1’s logic bricks but it applied the same filter on the same viewport twice. I also tried different filters. I’m using Blender 2.59 if it helps…
Please I really need help on this one.
Cheers, Dean
