Detailed Description
Container for GLSL matrix uniform variables.
XML Name
- uniform
XML attributes
| type | mat4 |
| name | Name of the variable in the shader program |
| as | Use OpenGL transformation state as the value |
Valid values for as attribute
- modelview
- projection
- modelviewprojection
- normal
- identity
In addition, UniformMatrix will automatically apply an 'as' attribute for several default names if it is not explicitly set in the scene file by the user. The names in the following list correspond to the values in the previous list.
Example
<program>
<shader file="shader.vert" />
<shader file="shader.frag" />
<uniform type="mat4" name="MVPMatrix" />
<cube />
</program>
Default names
- MVMatrix
- PMatrix
- MVPMatrix
- NormalMatrix
- IdentityMatrix
