Drawing exercise application

2022-05-05

• It shows an image and a drawing area. The user must copy the image to the drawing area.
• The application calculates how different the original image is to the drawed image.
• Value and color differences are calculated separaterly
• Two or more reference points can be marked to the image and they are shown in the drawing area
• Differences can be shown visually
• Brush strokes can be recorded and published to a site
• Users can submit their own images and their own brush stroke logs and compete who paints the image most accurately and in the shortest time
• The application can generate increasingly complex images
• The user must copy the images with certain time limits and accuracy to get the next image.
• There is an online hall of fame list for such generated images and their accepted brush stroke logs
• The images can be generated from a pseudo random generator so that they are identical for each user
• The application can render a 3d model in various angles
• By drawing the same model in different angels the user can learn it's shape
• A human body model with bending joints could also be implemeted to learn human anatomy
• 3d scanned real human models may be of better use for anatomy study
• A "toon" shader could be used to simplify the rendering so that it would be reasonably fast to copy the images
• A global illumination model could be used for rendering to study light behavior
