Member Enumeration Documentation

enum ion::gfxutils::ExternalShapeSpec::Format

The set of external geometry file formats that can be read with LoadExternalShape().

Enumerator
k3ds
kDae
kLwo
kObj
kOff
kUnknown

Definition at line 95 of file shapeutils.h.

enum ion::gfxutils::ExternalShapeSpec::IndexSize

The size of the vertex index data type.

Some platforms (OpenGL ES2) don't support 32-bit indices, resulting in an error when the shape is drawn.

Enumerator
k16Bit
k32Bit

Definition at line 105 of file shapeutils.h.

enum ion::gfxutils::ShapeSpec::VertexType

inherited

This enum is used to specify what per-vertex attributes should be included in a Shape.

Only the three geometric attributes available in the global registry ("aVertex", "aNormal", and "aTexCoords") are supported.

Enumerator
kPosition
kPositionTexCoords
kPositionNormal
kPositionTexCoordsNormal

Definition at line 55 of file shapeutils.h.

Referenced by ion::gfxutils::BuildBoxShape(), ion::gfxutils::BuildCylinderShape(), ion::gfxutils::BuildEllipsoidShape(), ion::gfxutils::BuildRectangleShape(), ion::gfxutils::BuildRegularPolygonShape(), and ion::gfxutils::LoadExternalShape().

bool ion::gfxutils::ExternalShapeSpec::center_at_origin

Whether to center the loaded object at the origin (defaults to true).

This centering is done in initial model space, before any transformations are applied.

Definition at line 111 of file shapeutils.h.

Referenced by ion::gfxutils::LoadExternalShape().

IndexSize ion::gfxutils::ExternalShapeSpec::index_size

The size of the vertex index data type.

Definition at line 117 of file shapeutils.h.

Definition at line 59 of file shapeutils.h.

float ion::gfxutils::ShapeSpec::scale

inherited

math::Point3f ion::gfxutils::ShapeSpec::translation

inherited

The order of operations is: scale, then rotate, then translate.

Definition at line 57 of file shapeutils.h.

gfx::BufferObject::UsageMode ion::gfxutils::ShapeSpec::usage_mode

inherited

UsageMode for all created BufferObject instances.

This also affects whether data is considered wipeable. (gfx::BufferObject::kStaticDraw).
