I asked this in the iPhone forum, but thought I'd give it a chance here instead. It seems Unity is setting precision specifiers automatically in GLSL ES shaders with no way of overriding (VERTEX_P as higp, FRAGMENT_P as mediump). This makes it really hard to squeeze out that extra bit of performance (since there is a 2x …
WebNov 26, 2012 · highp has a floating point magnitude range of 2^-62 to 2^62, and a floating point precision (relative) of 2^-16. Whereas mediump has a floating point magnitude … WebOpenGL ES exposes a precision modifier that allows control of the desired precision for different data types: highp, mediump and lowp. When used on floats, the mapping is typically as follows: highp - generally 32-bits (on some devices 24-bits in fragment shader) mediump - generally 16-bits lowp - generally 11-bits
Webuniform highp vec3 lightDirection; The actual range corresponding to a precision qualifier is dependent on the specific OpenGL ES implementation. Using a lower precision might have a positive effect on performance (frame rates) and power efficiency but might also cause a loss in rendering quality. A type qualifier is used in the OpenGL Shading Language (GLSL) to modify the storage or behavior of global and locally defined variables. These qualifiers change particular aspects of the variable, such as where they get their data from and so forth. They come in a number of different categories. Contents 1 … See more There are a large number of layout qualifiers which can be applied to a variety of defined constructs, from interface blocksto shader stage inputs and outputs. These affect the storage location of their data and many other … See more There is a way to qualify certain output variables as being invariant. This allows different programs to compute the exact same answer, assuming certain conditions are met. The invariantqualifier can be applied to an existing … See more There are three precision qualifiers: highp, mediump, and lowp. They have no semantic meaning or functional effect. They can apply to any floating-point type (vector or matrix), or … See more image variables, shader storage blocks, and the variables within a shader storage block can have a number of memory qualifiers applied to them. These affect how they can be used and how values read from/written to them … See more
