These older planet experiments are the ancestor of the Brush Planet algorithm based on my Planet Creator code.
This is a techdemo of a spherized cube looking much like a Temperate Planet. All done in Blitzmax+miniB3D. No subdividing, no shaders – just a clever use of high resolution detail textures and vertex alpha.
This is the nucleus of this game. A Microsoft Excel spreadsheet I've been working on the last three years. It calculates from the values in the orange fields in the upper left a complete Star System with 10 Planets and all of their properties using real physical formulas and some predefined tables.
This is a test if it is possible to create a nice looking 3D landscape to drive around with the Planet Exploration Vehicle (PEV).
