Using OpenFrameworks and C$++$ in Visual Studio:

$1)$ Create a TriangleShape as a subclass of Shape. This shape should have a position, rotation and scale parameters. The triangle shape when drawn should use a matrix transformation that uses these properties.

$2)$ Create a "heading vector" and draw it$.$ The heading vector indicates the direction of travel of the triangle. The vector should start at the position of the triangle $($near it's center$)$ and go through the top corner of the traingle $($in an isosceles triangle, the vector would be drawn through the corner with smallest angle$).$ The vector should be $2-3$X the height of the triangle.

$3)$ Support the functionality of "dragging" the triangle with the mouse. Only valid mouse down events inside the triangle should initiate dragging.

$4)$ Now support rotating the triangle using the LEFT and RIGHT arrow keys. The triangle should rotate in place around it's position $($roughly the center$).$ The heading vector should rotate with it$.$

$5)$ Now support moving the triangle forwards and backwards ALONG the heading vector. $($hint r$($t$)=$ o $+$ dt$).$ Use the UP$/$DOWN arrow keys for this.

$6)$ Create your own $.$PNG sprite image. It should have a transparent image and be non$-$circular so that you can easily tell if it is rotate.

$7)$ Create a new Shape called "ImageShape" derived from Shape which displayes an image instead of a traingle. The image should rotate around it's center.

$8)$ Support all the above functionality with the new ImageShape. $($heading vector and movement$).$ Note that for the purposes of selection with the mouse, you can use a bounding rectangle of the image for this assignment.

$9)$ Create a simple GUI panel with the following controls:

turn heading vector on$/$off $($toggle$)$

toggle between image shape or triangle shape

a float slider to control the scale $($of the triangle or image$).$
