Enumeration Type Documentation

CullMode

enum class t::CullMode

strong

Which faces to cull in the render.

Enumerator
None	Renders both front and back faces.
Front	Culls front faces.
Back	Culls back faces.

EulerRotationOrder

enum class t::EulerRotationOrder

strong

The Euler rotation order.

For example, EulerRotationOrder::Xyz means that the x rotation is applied first, then y, then z.

TextureFormat

enum class t::TextureFormat

strong

The texture format.

The integer associated with the format is the number of components in the texture. For example, TextureFormat::RgbDouble = 3 because it has 3 components (RGB).

Enumerator
RgbDouble	Stores RGB values in normalized floating-point values.
Depth	Stores the depth in normalized floating-point values.

Function Documentation

barycentric()

Vector3 t::barycentric	(	Vector3	point,
		Vector3	vertexA,
		Vector3	vertexB,
		Vector3	vertexC )

Computes and returns the barycentric coordinates of a point in a triangle.

Parameters

point	The point to compute the barycentric coordinates of.
vertexA	The first vertex of the triangle.
vertexB	The second vertex of the triangle.
vertexC	The third vertex of the triangle.

Returns

The barycentric coordinates of the point.

bresenham()

std::vector< std::pair< int, int > > t::bresenham	(	int	x0,
		int	y0,
		int	x1,
		int	y1 )

Computes and returns the points of a line using the Bresenham's line algorithm.

This implementation of the algorithm only uses integer arithmetic. As such, the input coordinates are expected to be integers.

Parameters

x0	The x-coordinate of the first point.
y0	The y-coordinate of the first point.
x1	The x-coordinate of the second point.
y1	The y-coordinate of the second point.

Returns

The list of points returned by the Bresenham's line algorithm.
