[ES 2.0] Cleanup #2

Posted Sunday, 12 July, 2009 - 16:48 by Inertia

Project:	The Open Toolkit library
Version:	1.0-beta-1
Component:	Code
Category:	task
Priority:	normal
Assigned:	Unassigned
Status:	closed

Nuke existing enum TextureTarget (it contains too many wrong tokens, rather start from scratch)
enum TextureTarget
{
Texture2D = ((int)0X0de1),
Texturecubemappositivex = ((int)0X8515),
Texturecubemapnegativex = ((int)0X8516),
Texturecubemappositivey = ((int)0X8517),
Texturecubemapnegativey = ((int)0X8518),
Texturecubemappositivez = ((int)0X8519),
Texturecubemapnegativez = ((int)0X851a),
}

Add to enum PixelType:
Unsignedbyte = ((int)0X1401),

Remove from enum PixelFormat:
Depthcomponent = ((int)0X1902), // according to spec p.60 it's not valid

Duplicate resulting PixelFormat enum and name the copy PixelInternalFormat.

Comments

Second part.

TODO:
-RenderbufferInternalformat looks good, but PixelInternalFormat may be flawed.

Done:
Investigate compressed texture formats:
The same mechanic as for ShaderBinary() is used, obtain number of formats by NUM_COMPRESSED_TEXTURE_FORMATS then obtain a list with COMPRESSED_TEXTURE_FORMATS. No references to formats besides DXT1 R5G6B5 and DXT1 RGB5A1 found.

Both are correct.

Remaining Issues:

BindTextureTarget and TextureTarget enums are heavily related to each other. (merge? the current approach might be inconvenient, but is safe.)

<enum name="BindTextureTarget">
  <token name="Texture2D" value="0X0de1" />
  <token name="TextureCubeMap" value="0X8513" />
</enum>
 
<enum name="TextureTarget">
  <token name="Texture2D" value="0X0de1" />
  <token name="TextureCubeMapPositiveX" value="0X8515" />
  <token name="TextureCubeMapNegativeX" value="0X8516" />
  <token name="TextureCubeMapPositiveY" value="0X8517" />
  <token name="TextureCubeMapNegativeY" value="0X8518" />
  <token name="TextureCubeMapPositiveZ" value="0X8519" />
  <token name="TextureCubeMapNegativeZ" value="0X851a" />
</enum>

TexParameter only accepts 4 tokens. It would make sense creating helpers or overloading it so enums like TextureMin(Mag)Filter can be used instead of enforcing (int) casts.

// example helpers:
void TexParameterMinFilter( TextureTarget target, TextureMinFilter filter );
void TexParameterMagFilter( TextureTarget target, TextureMagFilter filter );
void TexParameterWrapS( TextureTarget target, TextureWrapMode wrap );
void TexParameterWrapT( TextureTarget target, TextureWrapMode wrap );
 
TextureMinFilter GetTexParameterMinFilter( TextureTarget target );
TextureMagFilter GetTexParameterMagFilter( TextureTarget target );
TextureWrapMode GetTexParameterWrapS( TextureTarget target );
TextureWrapMode GetTexParameterWrapT( TextureTarget target );

Besides these issues (and probably some missing capital letters) this should work as-is.

Merged into es20 branch, rev. 2374.
