The shader editor edits Quake 3 shaders which can be found in:

Quake 3
Return to Castle Wolfenstein
Jedi Knight: Jedi Academy

And alot of other games. The program also has basic(Very) support for Doom 3 Shaders(Materials). The Shaders control how the textures are drawn, what blend effects to apply, if it should be rotated, stretched, etc. You can have layer on layer each with different effects. Quake 3's shaders show off the Q3 shaders the best.

To compile the program you need to install:

SynEdit By Michael Hieke
Url: http://synedit.sourceforge.net

Unihighlighter By Vitaly Nevzorov and Kirill Burtsev
Url: http://www.delphist.com/UniHighlighter.html

Program Limitations:
You can't add new shaders or delete them. You can't create a new shader file(only edit and save).

Zitat:

1.1
- revisions by Stucuk:
- Added: New, New Shader and Save As feature
- Added: Shader Error logging. All failed texture loads are recorded.
- Added: Environment position can now be changed (effects like glass are effected by this)
- Added: Fake lightmaps can be enabled to give a feel as to what the shader would look like with lightmaps
- Added: You can turn the shaders layers on and off, allowing you to "disect" the shader layer by layer.
- BugFix: Shader changes are fully "saved" (some edits were lost in 1.0)

To Do

Make it so user can see the shader on a 3d cube insted of a flat 2d image. with controls to rotate it (optional user choice)
Bumpmapping (Doom3 Style)
Doom3 Compatibility (I.E allowing things like 1 + time / 5... but would need bumpmapping to make it worthwhile)

Known Issues

Shader files with no actual shader definitions will cause an Access Violation

Below is the source to the program and some images. The images show the different layers of one shader. To show how they work, and how simpel they are. The advantage with "texture shaders" over animations is that there "perfectly animated". Animations with 4 seconds of animation would take about 100 frames (tv quality 25fps), each frame would have to be loaded into the computers memory. With "texture shaders" you would only need a max(iv never seen any reach this ammount) of 10 textures for any animation.

Description of the shader shown in the pics below:
Layer 1 - This base layer scrolls upwards
Layer 2 - This layer rotates and at the same time shrinks then grows (repeates)
Layer 3 - Same as layer 2
Layer 4 - Static

P.S one of the best shaders imo is textures\base_wall\q3tourneyscreen which can be found in Quake 3's base_wall.shader. If anyone improves this program, plz inform me.

1.2
- revisions by Stucuk:
- Added: 3d Square mode (allows you to see the deformations applied to some shaders)
- Added: Bumpmapping (tho it doesn’t work….)
- Added: When making a new file you can select if it’s a .shader or .mtr
- Changed: Fake lightmaps are on by default and are pure white
- BugFix: New and New Shader fixed.

Warning: For bumpmapping to work(well if someone could fix the programming) you need the 2 shader files from Sascha Willems's simplebump_v2 demo found Here

(bump_fp.txt and bump_vp.txt need to be placed in main\shader\ for bumpmapping to "work")

As said above the bumpmapping doesn't work, the output is always a black square. The tangents don't seem to be right... Included is a doom3 shader (modifyed) which if bumpmapping was working would show bumpmapping, there is also a nonbumpmap verson showing what the diffuse texture looks like. (Load -> Mod: Doom 3, Shader: Charactors)

You can download 1.2 here (1.44mb)

P.S if anyone finds out why bumpmapping doesn't work plz tell me.
Note: If bumpmapping worked you would need a GFX card that supports Fragment programs. for bumpmapping to do anything.

after looking at the simplebump_v2 i found some differences from my implementation, so i modifyed it to whats seen below..... but it is still black...

simplebump_v2:

Code:

 
// =============================================================================
//  TGLForm.RenderPath_ARBShader
// =============================================================================
//  Render path for ARB_Vertex_Program and ARB_Vertex_Shader. Needs PS2.0
//  support, but is most likely faster then the glSlang render path.
// =============================================================================
procedure TGLForm.RenderPath_ARBShader;
begin
glBindProgramARB(GL_VERTEX_PROGRAM_ARB, BumpVPARB);
glEnable(GL_VERTEX_PROGRAM_ARB);
glProgramLocalParameter4fARB(GL_VERTEX_PROGRAM_ARB, 0, LightPos.x,LightPos.y,LightPos.z,0);
glProgramLocalParameter4fARB(GL_VERTEX_PROGRAM_ARB, 1, 0,10,10,0);
 
glBindProgramARB(GL_FRAGMENT_PROGRAM_ARB, BumpFPARB);
glEnable(GL_FRAGMENT_PROGRAM_ARB);
glProgramLocalParameter4fARB(GL_FRAGMENT_PROGRAM_ARB, 0, 1/50,1/50,1/50,1/50); // invRadius
glProgramLocalParameter4fARB(GL_FRAGMENT_PROGRAM_ARB, 1, 0,0,0,0);    // ambient
 
// Bind base map to texture unit 0
glActiveTexture(GL_TEXTURE0);
glBindTexture(GL_TEXTURE_2D, DecalTex);
glEnable(GL_TEXTURE_2D);
// Bind normal map to texture unit 1
glActiveTexture(GL_TEXTURE1);
glBindTexture(GL_TEXTURE_2D, NormalMap);
glEnable(GL_TEXTURE_2D);
// Bind specular map to texture unit 2
glActiveTexture(GL_TEXTURE2);
glBindTexture(GL_TEXTURE_2D, SpecularMap);
glEnable(GL_TEXTURE_2D);
 
glClientActiveTexture(GL_TEXTURE0);
glActiveTexture(GL_TEXTURE0);
Primitive[PrimType].Render;
 
// Disable textures
glActiveTextureARB(GL_TEXTURE0_ARB);
glDisable(GL_TEXTURE_2D);
glActiveTextureARB(GL_TEXTURE1_ARB);
glDisable(GL_TEXTURE_2D);
glActiveTextureARB(GL_TEXTURE2_ARB);
glDisable(GL_TEXTURE_2D);
 
glDisable(GL_VERTEX_PROGRAM_ARB);
glDisable(GL_FRAGMENT_PROGRAM_ARB);
end;
 

Shader Editor:

Code:

 
glBindProgramARB(GL_VERTEX_PROGRAM_ARB, BumpVP);
glEnable(GL_VERTEX_PROGRAM_ARB);
glProgramLocalParameter4fARB(GL_VERTEX_PROGRAM_ARB, 0, LightPos.X,LightPos.Y,LightPos.Z,0);
glProgramLocalParameter4fARB(GL_VERTEX_PROGRAM_ARB, 1, 0,0,0,0);
 
glBindProgramARB(GL_FRAGMENT_PROGRAM_ARB, BumpFP);
glEnable(GL_FRAGMENT_PROGRAM_ARB);
glProgramLocalParameter4fARB(GL_FRAGMENT_PROGRAM_ARB, 0, 1/50,1/50,1/50,1/50); // invRadius
glProgramLocalParameter4fARB(GL_FRAGMENT_PROGRAM_ARB, 1, 0,0,0,0);    // ambient
 
// Bind base map to texture unit 0
glActiveTexture(GL_TEXTURE0);
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D, Shader.DiffuseMapID);
 
// Bind normal map to texture unit 1
glActiveTexture(GL_TEXTURE1);
glBindTexture(GL_TEXTURE_2D, Shader.BumpMapID);
glEnable(GL_TEXTURE_2D);
// Bind specular map to texture unit 2
glActiveTexture(GL_TEXTURE2);
glBindTexture(GL_TEXTURE_2D, Shader.SpecularMapID);
glEnable(GL_TEXTURE_2D);
 
{Render Code Below}
 
// Disable textures
glActiveTexture(GL_TEXTURE1);
glDisable(GL_TEXTURE_2D);
glActiveTexture(GL_TEXTURE2);
glDisable(GL_TEXTURE_2D);
glActiveTexture(GL_TEXTURE0);
//glDisable(GL_TEXTURE_2D);
 
glDisable(GL_VERTEX_PROGRAM_ARB);
glDisable(GL_FRAGMENT_PROGRAM_ARB);
 

simplebump_v2 Render code:

Code:

 
// Set vertex array
glVertexPointer(3, GL_FLOAT, 0, Vertex);
glEnableClientState(GL_VERTEX_ARRAY);
// Set normal array
glNormalPointer(GL_FLOAT, SizeOf(TglVertexTBN), @Tangent[0].Normal);
glEnableClientState(GL_NORMAL_ARRAY);
// Set texture coords array
glTexCoordPointer(2, GL_FLOAT, sizeof(TglVertexTBN), @Tangent[0].s);
glEnableClientState(GL_TEXTURE_COORD_ARRAY);
// Send sTangent on tex coord 1
glClientActiveTexture(GL_TEXTURE1);
glTexCoordPointer(3, GL_FLOAT, sizeof(TglVertexTBN), @Tangent[0].sTangent);
glEnableClientState(GL_TEXTURE_COORD_ARRAY);
glClientActiveTexture(GL_TEXTURE0);
// Send tTangent on tex coord 2
glClientActiveTexture(GL_TEXTURE2);
glTexCoordPointer(3, GL_FLOAT, sizeof(TglVertexTBN), @Tangent[0].tTangent);
glEnableClientState(GL_TEXTURE_COORD_ARRAY);
glClientActiveTexture(GL_TEXTURE0);
// Send Normaö on tex coord 3
glClientActiveTexture(GL_TEXTURE3);
glTexCoordPointer(3, GL_FLOAT, sizeof(TglVertexTBN), @Tangent[0].Normal);
glEnableClientState(GL_TEXTURE_COORD_ARRAY);
glClientActiveTexture(GL_TEXTURE0);
// Render
case primType of
 TglTorus : glDrawElements(GL_TRIANGLES, Length(Index), GL_UNSIGNED_INT, Index);
 TglPlane : glDrawElements(GL_QUADS, Length(Index), GL_UNSIGNED_INT, Index);
end;
 

Shader Editor Render code:

Code:

 
      glDisable(GL_CULL_FACE);
      glBegin(GL_TRIANGLES);
      For i := 0 to 5 do
      begin
glClientActiveTexture(GL_TEXTURE0);
glActiveTexture(GL_TEXTURE0);
 
      glNormal3f(V[i].Normal.X,V[i].Normal.Y,V[i].Normal.Z);
      glTexCoord2f(V[i].TextureCoord.X,V[i].TextureCoord.Y);
 
      glClientActiveTexture(GL_TEXTURE1);
      glTexCoord3f(Tan[i].sT.X,Tan[i].sT.Y,Tan[i].sT.Z);
      glClientActiveTexture(GL_TEXTURE0);
      // Send tTangent on tex coord 2
      glClientActiveTexture(GL_TEXTURE2);
      glTexCoord3f(Tan[i].tT.X,Tan[i].tT.Y,Tan[i].tT.Z);
      glClientActiveTexture(GL_TEXTURE0);
      // Send Normaö on tex coord 3
      glClientActiveTexture(GL_TEXTURE3);
      glTexCoord3f(V[i].Normal.X,V[i].Normal.Y,V[i].Normal.Z);
 
      glVertex3f(V[i].Position.X,V[i].Position.Y,V[i].Position.Z);
      end;
      glend;
 

It doesn't need to be done with the Arrays does it? (Vertex array, etc)
