This version is fun to play with because it is using the current mouse.
We draw this triangle wherever the mouse pointer is, so we can control the position by moving. This shows one line in the triangle - at its actual size, and magnified 6x. Triangle and quad strips are handy if you want to draw circle segments or ribbons in a 3D environment. Quad strips are similar, but they are a series of connected quads.

#Processing triangle pmouse how to#
So I am very confused on how to make a triangle and a custom shape follow my cursor, with ellipses and rectangles it is very simple because I can just switch the x and y values to mouseX and mouse Y,īut with a triangle I do not want to change anything about the shape I just want it to follow the cursor but I am clueless on how to do that, same thing goes for the custom shape I do not know how to make it follow my cursor. Then we draw a triangle that represents a small space ship. Triangle strips are a series of connected triangles.
