Re: [osg-users] geometry shader with opengles
Hi,
I have succeeded on Android ,But not well on IOS,whether it is iphone4 or 6p or
6sp...
they all show: version '310' is not supported
(geometry shader only works on es3.1 later)
But version 300 is OK(but couldn't use geometry shader),So is there somthing i
missed?
code now like this:
#version 310 es
#extension GL_EXT_geometry_shader : enable
uniform mat4 osg_ModelViewMatrix;
uniform mat4 osg_ViewMatrix;
uniform mat4 osg_ProjectionMatrix;
uniform mat4 osg_ViewMatrixInverse;
uniform float TubeRadius;
uniform int EdgeCount;
uniform vec3 DirLightDir_V3;
layout(points) in;
layout(triangle_strip, max_vertices = 4) out;
out vec2 gf_uv;
void main()
{
vec4 offset0 = vec4(0,0,0,0);
vec4 offset1 = vec4(1,0,0,0);
vec4 offset2 = vec4(1,1,0,0);
vec4 offset3 = vec4(0,1,0,0);
gl_Position = osg_ProjectionMatrix * (gl_in[0].gl_Position + offset0);
gf_uv = offset0.xy;
EmitVertex();
gl_Position = osg_ProjectionMatrix * (gl_in[0].gl_Position + offset1);
gf_uv = offset1.xy;
EmitVertex();
gl_Position = osg_ProjectionMatrix * (gl_in[0].gl_Position + offset3);
gf_uv = offset3.xy;
EmitVertex();
gl_Position = osg_ProjectionMatrix * (gl_in[0].gl_Position + offset2);
gf_uv = offset2.xy;
EmitVertex();
EndPrimitive();
}
Thank you!
Cheers,
lin

[osg-users] geometry shader with opengles
Hi,
I want to know if osg support geometry shader with opengles3.2?I have changed
the profile to GLES3.I'm now testing on IOS.
I have info like this:
GEOMETRY glCompileShader "" FAILED
GEOMETRY Shader "" infolog:
ERROR: 0:15: 'layout' : syntax error: syntax error
and this is my code:
#version 300 es
precision highp float;
precision highp int;
uniform mat4 osg_ModelViewMatrix;
uniform mat4 osg_ViewMatrix;
uniform mat4 osg_ProjectionMatrix;
uniform mat4 osg_ViewMatrixInverse;
uniform float TubeRadius;
uniform int EdgeCount;
uniform vec3 DirLightDir_V3;
layout(points) in;
layout(triangle_strip, max_vertices = 4) out;
out vec2 gf_uv;
void main()
{
vec4 offset0 = vec4(0,0,0,0);
vec4 offset1 = vec4(1,0,0,0);
vec4 offset2 = vec4(1,1,0,0);
vec4 offset3 = vec4(0,1,0,0);
gl_Position = osg_ProjectionMatrix * (gl_in[0].gl_Position + offset0);
gf_uv = offset0.xy;
EmitVertex();
gl_Position = osg_ProjectionMatrix * (gl_in[0].gl_Position + offset1);
gf_uv = offset1.xy;
EmitVertex();
gl_Position = osg_ProjectionMatrix * (gl_in[0].gl_Position + offset3);
gf_uv = offset3.xy;
EmitVertex();
gl_Position = osg_ProjectionMatrix * (gl_in[0].gl_Position + offset2);
gf_uv = offset2.xy;
EmitVertex();
EndPrimitive();
}
Any help is welcome！
Thank you!
Cheers,
