"Single precision: 24 bits" What?! You say that's in the floating point section? Ok... 24 bits would mean: 2^24 = 16777216 For an unsigned integer in binary, there are 1677... 2 Feb 2010 21:54
1D to 3D coordinate translation. (No 16 million is right ?!) Ok I think the ixbtlabs article is wrong after all... (4095 * 4095)-1 seems to work just fine... My project has problem though... I need to be able to multiply 8000*8000... which is apperently way out of range... I might have to do manual multiplication algorithm somehow to make it work... Bye, Sk... 2 Feb 2010 14:25
Intel documentation mistake for single floating point precision ! (Nope oops lol) Nope, it's not a mistake... I made a mistake... 8000*8000 is way over 24 bits ! ;) :) I checked with this calculator: http://www.h-schmidt.net/FloatApplet/IEEE754.html And also by doing (2^24) ^ 0.5 = 4096 So: (4095 * 4095)-1 is still in range ! ;) Bye, Skybuck =D ... 2 Feb 2010 14:25
Intel documentation mistake for single floating point precision ! Intel document: " The IA-32 Intel Architecture Software Developer's Manual, Volume 1, Basic Architecture, Document Number 253665 rev 19.pdf" Contains a serious mistake on page 4-5: " Table 4-2. Length, Precision, and Range of Floating-Point Data Types " It reads: " Single precision: 24 bits " ... 2 Feb 2010 14:25
1D to 3D coordinate translation. (testing hardware precision for 3d textures and inprecise 3d texture coordinates) Remaining question is: What does the hardware do when it encounters an inprecise 3D texture coordinate ? For example instead of: 0, 0, 0.265 it encounters: 0, 0, 0.2649999856948853 (53/200 in 32 bit floating point) The hardware "knows" the texture is 500x400x200 If the hardware is inprecise it w... 2 Feb 2010 14:25

Optimization Question: Dynamic ByteArray[ Offset Calculation ] vs (Pointer + Offset Calculation) Hello, I wonder if the following code might produce different results in Delphi: var a : pointer; // pointer to array a b : array of byte; // pointer to array b p : pointer; begin p := pointer( a + offset calculation (multplication involved) ); vs p := @b[ offset calculation (mu... 2 Feb 2010 14:25
