They are commonly used to give texture to models, renders, or environments in animation or video games. [1] These textures are created by artists or designers using bitmap editor software such as Adobe Photoshop [ 2 ] or GIMP , [ 3 ] or simply by scanning an image and, if necessary, retouching it on a personal computer .
The water is typically neutral to slightly acidic, [4] [14] but the pH can range between 4.5 [8] and 8. [2] In the Amazon basin, clearwater rivers flowing through regions with sediments of Tertiary age are typically highly acidic, while those flowing through sediments of Carboniferous age are closer to neutral or slightly basic.

Texture compression is a specialized form of image compression designed for storing texture maps in 3D computer graphics rendering systems. Unlike conventional image compression algorithms, texture compression algorithms are optimized for random access. Texture compression can be applied to reduce memory usage at runtime.
The original 'ETC1' compression scheme provides 6x compression of 24-bit RGB data. It does not support the compression of images with Alpha components, although there are work-arounds for this. [3] ETC1 takes 4x4 groups of pixel data and compresses each into a single 64-bit word. The 4×4 pixel group is first divided into two 4×2 chunks ...
How clear the water appears is only one component of water quality. [1] [5] [47] An underwater ecosystem can have high water clarity yet low water quality, and vice versa. Scientists have observed that many lakes are becoming less clear while also recovering from acid rain. This phenomenon has been seen in the northeastern United States and ...
All convert a 4×4 block of pixels to a 64-bit or 128-bit quantity, resulting in compression ratios of 6:1 with 24-bit RGB input data or 4:1 with 32-bit RGBA input data. S3TC is a lossy compression algorithm, resulting in image quality degradation, an effect which is minimized by the ability to increase texture resolutions while maintaining the ...
The same water in a smaller bucket looks only slightly cyan, [1] and observing the water at close range makes it appear colorless to the naked eye. The intrinsic color of liquid water may be demonstrated by looking at a white light source through a long pipe that is filled with purified water and closed at both ends with a transparent window.
[7] [8] [9] The system lies mainly under the western margins of Gunung Api between the Melinau Gorge and Cave of the Winds. The first exploration by speleologists was during the 1977/78 Royal Geographical Society Mulu Sarawak Expedition when 24 km (15 mi) of the cave passage were surveyed. Many expeditions have increased the explored length and ...
