Member Enumeration Documentation

◆ Format

enum ImFusion::GL::InternalFormat::Format

List of all supported internal formats.

These are essentially all non-special (e.g. packed, compressed) formats mandated by OpenGL 3.3. Using other OpenGL image formats than those of this enum is not supported by ImFusionGL.

Member Function Documentation

◆ isColorRenderable()

bool ImFusion::GL::InternalFormat::isColorRenderable ( ) const

Returns whether the format can be used as a framebuffer attachment.

This limitation only exists with OpenGL ES. With regular OpenGL, all formats are color renderable.

◆ isTextureFilterable()

bool ImFusion::GL::InternalFormat::isTextureFilterable ( ) const

Returns whether the format supports linear filtering.

This limitation only exists with OpenGL ES. With regular OpenGL, all formats support linear filtering.
