rohestheater-logo-rotate

Code for rotating rohestheater logo animation

Demo

Structure

This repository mainly consists of the three Red files

• ./perspective.red
• ./rohestheater-logo-rotate.red
• ./utils.red.

The file utils.red supplies some helping functions. The file perspective.red contains some functions that can be used to calculate a 3x3 matrix that performs a perspective transformation. The rohestheater-logo-rotate.red file makes use of this matrix to tranform a rotated virtual 2D-grid to a position and orientation in 3-dimensional space to project it back to a series of 2D-images. Afterwards the 'rohestheater'-title is put upon that grid so that it is always fully surrounded by the borders of the (rotated) grid.

Todo

• Test if the virtual 2D-grid can be smaller when replacing pair! with point2D! for internal calculations, as pair! enforces conversion to positive integers.
• Try using point2D! as result of tilt -> omits the need for up- and downscaling!
• Center virtual 2D-grid around (0, 0)
• Use as- instead of to-, as it has cleaner syntax and might be faster
• Try to calculate the 1920x1080-sized output-image internally
• Make GIF animation for use in README
• Re-observe target points for perspective transform
• Implement the perspective-functions in Red/System for additional performance
