Function Documentation

int cugl::addMaterial	(	GLfloat	ambR,
		GLfloat	ambG,
		GLfloat	ambB,
		GLfloat	ambA,
		GLfloat	difR,
		GLfloat	difG,
		GLfloat	difB,
		GLfloat	difA,
		GLfloat	speR,
		GLfloat	speG,
		GLfloat	speB,
		GLfloat	speA,
		GLfloat	shine
	)

Add a material to the set of built-in materials. The array of material has a fixed size of 100. An attempt to create more than 100 materials will fail. The parameters specify:

• RGBA values for ambient light
• RGBA values for diffuse light
• RGBA values for specular light
• Value for shininess exponent

  Returns

  the index of the new material.

int cugl::addMaterial

(

GLfloat

params[]

)

Add a material to the set of built-in materials. The array of material has a fixed size of 100. An attempt to create more than 100 materials will fail.

Parameters

params

specifies: RGBA values for ambient light RGBA values for diffuse light RGBA values for specular light Value for shininess exponent

Returns

the index of the new material.

void cugl::axes

(

GLfloat

size = 1

)

Todo:

Models should probably be put into a separate file.

Draw coordinate axes. This function draws the three principal axes in the current position, using size to determine the length of each axis. The axes are colour-coded: X = red, Y = green, Z = blue.

void cugl::buildPlane

(

bool

shadow = false

)

Draw an aircraft. The argument determines whether the plane is drawn with a metallic colour (shadow = false, the default) or black, to act as a shadow (shadow = true). The aircraft is built using Bezier surfaces. If you use glScalef to change its size, you must enable GL_NORMALIZE to correct the normals. Otherwise, the lighting will be wrong.

GLuint cugl::makePlaneList

(

bool

shadow = false

)

Construct a GL call list for the aircraft and return its index.

void cugl::setMaterial	(	const int	m,
		GLenum	face = GL_FRONT
	)

Set material values from the enumeration.

Parameters

m	is chosen from the enumeration MATERIAL
face	should be one of GL_FRONT (the default), GL_BACK, or GL_FRONT_AND_BACK.
