This struct contains specifications common to all basic shapes.

math::Anglef latitude_start

math::Anglef latitude_end

IndexSize index_size

The size of the vertex index data type.

Angle< float > Anglef

Type-specific typedefs.

Matrix< 3, float > Matrix3f

External geometry formats.

const gfx::ShapePtr BuildEllipsoidShape(const EllipsoidSpec &spec)

Builds and returns a Shape representing an axis-aligned ellipsoid.

gfx::BufferObject::UsageMode usage_mode

UsageMode for all created BufferObject instances.

const gfx::ShapePtr BuildCylinderShape(const CylinderSpec &spec)

Builds and returns a Shape representing an axis-aligned cylinder.

math::Anglef longitude_start

const gfx::IndexBufferPtr BuildWireframeIndexBuffer(const gfx::IndexBufferPtr &tri_index_buffer)

Public functions.

const gfx::ShapePtr LoadExternalShape(const ExternalShapeSpec &spec, std::istream &in)

Loads a Shape with the specified format from the passed stream.

math::Anglef longitude_end

VertexType

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

const gfx::ShapePtr BuildRegularPolygonShape(const RegularPolygonSpec &spec)

Builds and returns a Shape representing a flat regular polygon.

Format

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

const gfx::ShapePtr BuildBoxShape(const BoxSpec &spec)

Builds and returns a Shape representing an axis-aligned box.

IndexSize

The size of the vertex index data type.

PlaneNormal

This enum specifies the principal Cartesian plane containing the rectangle by its directed normal...

bool center_at_origin

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

math::Point3f translation

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

base::AllocatorPtr allocator

const gfx::ShapePtr BuildRectangleShape(const RectangleSpec &spec)

Builds and returns a Shape representing a rectangle in one of the principal Cartesian planes...
