Function Documentation

◆ ccGLBindTexture2D()

void CC_DLL ccGLBindTexture2D ( GLuint  textureId)

If the texture is not already bound to texture unit 0, it binds it.

If CC_ENABLE_GL_STATE_CACHE is disabled, it will call glBindTexture() directly.

Since
v2.0.0

◆ ccGLBindTexture2DN()

void CC_DLL ccGLBindTexture2DN ( GLuint  textureUnit,
GLuint  textureId 
)

If the texture is not already bound to a given unit, it binds it.

If CC_ENABLE_GL_STATE_CACHE is disabled, it will call glBindTexture() directly.

Since
v2.1.0

◆ ccGLBindVAO()

void CC_DLL ccGLBindVAO ( GLuint  vaoId)

If the vertex array is not already bound, it binds it.

If CC_ENABLE_GL_STATE_CACHE is disabled, it will call glBindVertexArray() directly.

Since
v2.0.0

◆ ccGLBlendFunc()

void CC_DLL ccGLBlendFunc ( GLenum  sfactor,
GLenum  dfactor 
)

Uses a blending function in case it not already used.

If CC_ENABLE_GL_STATE_CACHE is disabled, it will the glBlendFunc() directly.

Since
v2.0.0

◆ ccGLBlendResetToCache()

void CC_DLL ccGLBlendResetToCache ( void  )

Resets the blending mode back to the cached state in case you used glBlendFuncSeparate() or glBlendEquation().

If CC_ENABLE_GL_STATE_CACHE is disabled, it will just set the default blending mode using GL_FUNC_ADD.

Since
v2.0.0

◆ ccGLDeleteProgram()

void CC_DLL ccGLDeleteProgram ( GLuint  program)

Deletes the GL program.

If it is the one that is being used, it invalidates it. If CC_ENABLE_GL_STATE_CACHE is disabled, it will the glDeleteProgram() directly.

Since
v2.0.0

◆ ccGLDeleteTexture()

void CC_DLL ccGLDeleteTexture ( GLuint  textureId)

It will delete a given texture.

If the texture was bound, it will invalidate the cached. If CC_ENABLE_GL_STATE_CACHE is disabled, it will call glDeleteTextures() directly.

Since
v2.0.0

◆ ccGLDeleteTextureN()

void CC_DLL ccGLDeleteTextureN ( GLuint  textureUnit,
GLuint  textureId 
)

It will delete a given texture.

If the texture was bound, it will invalidate the cached for the given texture unit. If CC_ENABLE_GL_STATE_CACHE is disabled, it will call glDeleteTextures() directly.

Since
v2.1.0

◆ ccGLEnable()

void CC_DLL ccGLEnable ( ccGLServerState  flags)

It will enable / disable the server side GL states.

If CC_ENABLE_GL_STATE_CACHE is disabled, it will call glEnable() directly.

Since
v2.0.0

◆ ccGLEnableVertexAttribs()

void CC_DLL ccGLEnableVertexAttribs ( unsigned int  flags)

Will enable the vertex attribs that are passed as flags.

Possible flags: 

 kCCVertexAttribFlag_Position
 kCCVertexAttribFlag_Color
 kCCVertexAttribFlag_TexCoords

These flags can be ORed. The flags that are not present, will be disabled.

Since
v2.0.0

◆ ccGLInvalidateStateCache()

void CC_DLL ccGLInvalidateStateCache ( void  )

Invalidates the GL state cache.

If CC_ENABLE_GL_STATE_CACHE it will reset the GL state cache.

Since
v2.0.0

◆ ccGLUseProgram()

void CC_DLL ccGLUseProgram ( GLuint  program)

Uses the GL program in case program is different than the current one.

If CC_ENABLE_GL_STATE_CACHE is disabled, it will the glUseProgram() directly.

Since
v2.0.0

◆ ccSetProjectionMatrixDirty()

void CC_DLL ccSetProjectionMatrixDirty ( void  )

sets the projection matrix as dirty

Since
v2.0.0
