Fragment of full-color image (left) vs Amiga HAM (right) Hold-And-Modify, [1] [2] [3] usually abbreviated as HAM, [4] is a display mode of the Amiga computer. [5] It uses a highly unusual technique to express the color of pixels, allowing many more colors to appear on screen than would otherwise be possible.
Amiga Advanced Graphics Architecture (AGA) is the third-generation Amiga graphic chipset, first used in the Amiga 4000 in 1992. Before release AGA was codenamed Pandora by Commodore International. AGA was originally called AA for Advanced Architecture in the United States. The name was later changed to AGA for the European market to reflect ...
The number of color registers is a hardware limitation of pre-AGA chipsets in Amiga computers. Some contemporary games ( Fusion , [ 9 ] Defender of the Crown , [ 10 ] Agony , [ 11 ] Lotus II , [ 12 ] or Unreal [ 13 ] ) and animations ( HalfBrite Hill [ 4 ] ) use EHB mode as a hardware-assisted means to display shadows or silhouettes.
The Original Chip Set (OCS) of the Commodore Amiga features a 12-bit RGB, 4,096-color palette. As the Amiga Copper programmable graphics coprocessor is capable of changing color lookup table entries on the fly during display, in practice the number of distinct colors visible on-screen may exceed static color lookup table sizes documented here.
Retargetable graphics [1] [2] (abbreviated as RTG) is a device driver API mainly used by third-party graphics hardware to interface with AmigaOS via a set of libraries. [3] The software libraries may include software tools to adjust resolution , screen colors, pointers , and screenmodes.
Amiga Chip Set. The Original Chip Set (OCS) is a chipset used in the earliest Commodore Amiga computers and defined the Amiga's graphics and sound capabilities. It was succeeded by the slightly improved Enhanced Chip Set (ECS) and the greatly improved Advanced Graphics Architecture (AGA).
The latest Amiga version (3.59) was released in 1994 and distributed publicly, although the source code was kept proprietary. It remains a valid graphic program and continues to be used [when?] despite its age due to its ease of use and vast number of features. Programs like Candy Factory for AOS 4.0 are designed to create special effects for ...
The other was a true-color package called TrueBrilliance. [2] [3] [4] The Brilliance package was one of the major rivals to Deluxe Paint, the established "killer app" in Amiga bitmap graphics editing. At its launch, Brilliance attracted generally favorable reviews. [5]
