Аннотация: In this paper, we present an extended stream processors texture generation
model for displaying educational content in 3D virtual worlds. The model suggests conducting
image-processing tasks on stream processors in order to reduce the load on CPU. The main
objective of the paper is to provide the evaluation results of the suggested extended model
based on a series of tests. The extension of the model consists of using fixed pipeline features
of stream processors. The obtained results of performance evaluation confirm high efficiency
and veracity of the generalized mathematical and programming models for image processing.
High performance can be explained by specificity problem of generating educational content
for virtual words because the source data for the synthesis of images and the data area for the
resultant images are in the local memory of stream processors.
