bjorneek / teapot-os

A scratch built kernel original planed to only render a Utah-teapot

teapot-OS

(sine wave animation) (first 3d renderer, with mouse controll)

Current progress

• Bootloader enter 32 bit protected mode and run c code
• Switch VGA mode the should bootloader set the VGA mode to 320 x 200 color
• Drawing on screen create a VGA driver adding a layer of abtraction to v-ram acces
• Graphics library enable features like fill_rect and draw_triangle via the VGA driver
• Interrupts handle interrupts in order to create drivers for mouse and keyboard
• Keyboard driver enable keyboard input with information about keypresses
• Font create a custom 7x5 font in preparation for text output
• Text output enable the VGA driver to draw font characters
• String output add draw_string to graphics library by converting chars to font indexes
• Mouse driver enable mouse motion and button input
• Cursor [temporary] implement mouse cursor directly to VGA driver
• GUI [temporary] use available functions display keyboard and mouse input info
• Clean up VGA driver differentiate more between VGA driver and graphics lib
• Linear algebra port library from this project in preparation for 3D rendering
• 3D-renderer implement 3D-renderer
• Event handeler create a event handeler to interface with device drivers
• Memory allocator create a memory allocator
• Run on hardware run teapot os natively on real hardware (potentialy 2013 MacBook Air)

---

• standard library create neccesary utilities
  • Fixed width ints for neater code
  • Graphics library
  • String utils converting and concating
  • Math math functions especialy trigonometry functions like sin(x)
