List of all members.

Public Types

• enum { target = GLTextureTarget<Dims>::target }

Public Member Functions

• override void bind (int i=0)

  Sets the active texture unit and calls glBindTexture() .
  

• int BitsPerTexel () const

  return bits per texel, if known
  

• void disable () const

  Call glDisable()
  

• void enable (int i=0)

  Call glEnable()
  

• GLTexture (const MemCore::WeakPtr< MemCore::Creature > &C, int textureUnit=0)

  Creation of texture placeholder; does not need to be called from an OpenGL Context.
  

• GLuint nElements (int n=0) const

  Return the number of texel elements stored in the nth texture.
  

• void setTexParameters (int i=0)

  Sets the texture parameters for the ith texture.
  

• const GLuint * Size (int i=0) const

  The dimension of this texture.
  

• void TexParameterf (GLenum pname, GLfloat param, int i=0)

  Sets an OpenGL texture parameter.
  

• void TexParameterf (GLenum pname, const GLfloat *params, int i=0)
• void TexParameteri (GLenum pname, GLint param, int i=0)
• void TexParameteri (GLenum pname, const GLint *params, int i=0)
• ~GLTexture ()

  Destructor.
  

Public Attributes

• GLenum TextureMaxFilter [N]

  Texture max filter, set to GL_LINEAR initially Set by setTexParameters().
  

• GLenum TextureMinFilter [N]

  Texture min filter, set to GL_NEAREST initially. Set by setTexParameters().
  

• Eagle::Vector< double, Dims > TextureOffset [N]

  Offset for texture coordinates.
  

• Eagle::Vector< double, Dims > TextureScale [N]

  For each texture stored here, provide some scaling info on the fractional part that is utilized here.
  

• GLenum TextureWrap [N][Dims]

  Texture wrap parameter, for each texture and texture coordinates.
  

Protected Member Functions

• TextureID< N > & me ()
• void setTexParametersNoBind (int i=0) const

  Sets the texture parameters for the ith texture, but doesn't call bind() before.
  

Protected Attributes

• int bits_per_texel
• GLuint Extension [N][Dims]

Member Enumeration Documentation

anonymous enum

Enumerator:

target

The corresponding OpenGL texture target (GL_TEXTURE_nD)

---

Member Function Documentation

override void Wizt::GLTexture::bind

(

int

i = 0

)

[inline]

Sets the active texture unit and calls glBindTexture() .

Note that the texture won't be enabled yet for rendering, just bound for subsequent texture operations.

Reimplemented in Wizt::Cubemap.

void Wizt::GLTexture::TexParameterf	(	GLenum	pname,
		GLfloat	param,
		int	i = 0
	)		[inline]

Sets an OpenGL texture parameter.

Parameters:

pname

Specifies the symbolic name of a single-valued texture parameter. pname can be one of the following: GL_TEXTURE_MIN_FILTER, GL_TEXTURE_MAG_FILTER, GL_TEXTURE_MIN_LOD, GL_TEXTURE_MAX_LOD, GL_TEXTURE_BASE_LEVEL, GL_TEXTURE_MAX_LEVEL, GL_TEXTURE_WRAP_S, GL_TEXTURE_WRAP_T, GL_TEXTURE_WRAP_R, or GL_TEXTURE_PRIORITY.

Note:

Call SelectActiveTextureUnit() before invoking these functions.

Member Data Documentation

GLenum Wizt::GLTexture::TextureWrap[N][Dims]

Texture wrap parameter, for each texture and texture coordinates.

Initially, those are set to GL_CLAMP. The texture parameters are set by calling setTexParameters().
