| 1 | Use of GLSL for vertex and fragment programs in Qt

|

| 4 | We don't compile the *.glsl files because we don't want the build process of
|
|---|
| 5 | Qt to require cgc from nVidia to build the fragment programs.
|

| 6 |
|
|---|
| 7 | The script src/opengl/util/glsl_to_include.sh will compile a GLSL program to a file
|
|---|
| 8 | that can be included in a C(++) program. The file is the output from cgc
|
|---|
| 9 | quoted as a string.
|
|---|
| 10 |
|
|---|
| 11 | This can be done manually by:
|
|---|
| 12 |
|
|---|
| 13 | ./glsl_to_include.sh radial.glsl
|
|---|
| 14 | ./glsl_to_include.sh conical.glsl
|
|---|
| 15 |
|
|---|
| 16 | This will produce the files radial.frag and radial.glsl_quoted.
|
|---|
| 17 | (and also conical.frag and conical.glsl_quoted)
|
|---|
| 18 | These files are included by qpaintengine_opengl.cpp
