Member Function Documentation

draw()

MYGL_EXPORT void draw ( const glm::mat4 & lookAt, const glm::mat4 & projection ) const

overridevirtual

Draws the triangle, this method is called by a window.

Parameters

lookAt	The view matrix (usually provided by the window)
projection	The projection matrix (also provided by the window)

Implements AbstractShape.

setPosition() [1/2]

MYGL_EXPORT void setPosition ( const glm::vec2 & pos, bool center = false )

overridevirtual

Moves the triangle to a specified position.

Parameters

pos	A glm::vec2 containing the new position
center	If true, set the triangle's centroid at 'pos', else sets its bottom left hand corner. Default value is false

Reimplemented from AbstractShape.

setPosition() [2/2]

MYGL_EXPORT void setPosition ( int x, int y, bool center = false )

overridevirtual

Moves the triangle to (x,y)

Parameters

x	The new horizontal position
y	The new vertical popsition
center	If true, set the triangle's centroid at (x,y), else sets its bottom left hand corner at (x,y). Default value is false

Reimplemented from AbstractShape.
