GLScry Description

Free and open source OpenGL performance analysis utility GLScry is a high-level OpenGL performance analysis tool, developed under the supervision of Dr. Dirk Reiners at Iowa State University. It provides a set of low-level benchmarking primitives and a Python interface for writing high-level tests to measure things such as fill rate with different states enabled, state change costs, vertex cache effect, texture upload rates vs. format, existence of early Z techniques, cost of lights, performance of vertex buffer formats, etc. NOTE: GLScry is licensed and distributed under the terms of the GNU Library or Lesser General Public License (LGPL). What's New in This Release: · Replaced old statechange.py with new one. · Added a new test for comparing state changes side by side. · Add a statechange for uniforms test. · Added support for uniforms on the shader state. · Store different build options files based on the platform. · Added a transform test. · Upgrade to new glew and add data types test. · Added a test for triangle lists. · Upgraded to Boost 1.32 · Sort the tests after they're globbed by run.py. · Added support for multiple batches in one Geometry. Then added a test for multiple triangle strips vs. joining with degenerate triangles. · Moved batchSize attribute from GeometryTest to Geometry. · Added documentation. · Added support for measuring geometry data rate. · Added a fragment shader test. · Added a shader switch test. · Added a GLSL ShaderState. · Got rid of DisplayListTest in lieu of ImmediateTest.useList · Got rid of CompiledVertexArrayTest in lieu of a flag on VertexArrayTest. · Add multitexturing support to the TextureState class.
