20.500.12556/RUL-169471 Vzporedna kompresija tekstur v formatu BC1 z vmesnikom WebGPU Parallel compression of BC1 textures using WebGPU Naloga obravnava paralelne metode kompresije tekstur v formatu BC1 (DXT1) za uporabo v realnem času, s ciljem učinkovitejšega shranjevanja in prikaza teksturiranih trikotniških modelov. Razviti so bili štirje pristopi, ki temeljijo na izbiri osnovnih barv v posameznem 4 × 4 bloku: pristop min-max, pristop z metodo PCA, naključni pristop (iskanje barv z naključnim vzorčenjem) ter pristop, ki temelji na gručenju barv. Za ovrednotenje kakovosti kompresije so uporabljene metrike MSE, PSNR, SSIM in CIEDE2000, ki merijo, v kolikšni meri rekonstruirana tekstura ohranja vizualne značilnosti izvirnika. Vse metode so implementirane s tehnologijo WebGPU in optimizirane za čim hitrejše izvajanje na grafičnih procesorjih, pri čemer so uporabljeni računski senčilniki. Izvedena je bila performančna analiza vseh pristopov ter primerjava z orodjema za kompresijo NVIDIA Texture Tools in AMD Compressonator. The thesis examines parallel texture compression methods in the BC1 (DXT1) format for real-time use, aiming for more efficient storage and display of textured triangular models. Four approaches were developed based on the selection of base colors in each 4 × 4 block: the min-max approach, the PCA approach, the random approach (searching for colors through random sampling), and the approach based on color clustering. To evaluate the quality of compression, metrics MSE, PSNR, SSIM, and CIEDE2000 were used, which measure the extent to which the reconstructed texture preserves the visual characteristics of the original. All methods are implemented using WebGPU technology and optimized for the fastest possible execution on graphics processors, utilizing compute shaders. A performance analysis of all approaches was conducted and a comparison with the compression tools NVIDIA Texture Tools and AMD Compressonator, was performed. kompresija tekstur BC1 DXT1 PCA MSE PSNR SSIM CIEDE2000 CIELAB gručenje texture compression BC1 DXT1 PCA MSE PSNR SSIM CIEDE2000 CIELAB clustering true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-05-29 14:10:06 2025-05-29 14:10:23 2025-06-16 05:41:09 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 37982 239398403 Cigler_Alen_-_Vzporedna_kompresija_tekstur_v_formatu_BC1_z_vmesnikom_WebGPU.pdf Cigler_Alen_-_Vzporedna_kompresija_tekstur_v_formatu_BC1_z_vmesnikom_WebGPU.pdf 1 0036D6DC9CE172FAD98F3A8AF70F1B6E e0b7e4c067aae506ad6b2f3ae4cfc07003ee94a3b50b5e7b7ea599ad71b7f203 9a541f0a-3c84-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=210878 Fakulteta za računalništvo in informatiko 0 0 0
