Detailed Description

Most basic/generic texture: only contains a texture ID.

Current implementation always assumes 2D textures.

Constructor & Destructor Documentation

openmsx::Texture::Texture ( )

Default constructor, allocate a openGL texture name.

Definition at line 38 of file GLUtil.cc.

References disableInterpolation(), and textureId.

openmsx::Texture::Texture ( Texture && other )

inline

Move constructor and assignment.

Definition at line 43 of file GLUtil.hh.

openmsx::Texture::~Texture ( )

Release openGL texture name.

Definition at line 44 of file GLUtil.cc.

References textureId.

Member Function Documentation

void openmsx::Texture::bind ( )

inline

Makes this texture the active GL texture.

The other methods of this class and its subclasses will implicitly bind the texture, so you only need this method to explicitly bind this texture for use in GL function calls outside of this class.

Definition at line 61 of file GLUtil.hh.

References textureId.

void openmsx::Texture::disableInterpolation ( )

Disables bilinear interpolation for this texture and uses nearest neighbour instead.

Definition at line 56 of file GLUtil.cc.

References bind().
