From 3.9.2. Conversion from Floating-Point to Normalized Fixed-Point

The conversion from a floating-point value f to the corresponding unsigned normalized fixed-point value c is defined by first clamping f to the range [0,1], then computing

c = convertFloatToUint(f × (2b - 1), b)

where convertFloatToUint(r,b) returns one of the two unsigned binary integer values with exactly b bits which are closest to the floating-point value r. Implementations should round to nearest. If r is equal to an integer, then that integer value must be returned. In particular, if f is equal to 0.0 or 1.0, then c must be assigned 0 or 2b - 1, respectively.

After 2 days of fixing this I got an answer. Part of angular.json with pror architect must be next:

The artifacts are caused by the lack of precision in shaders on different devices. Using precision highp float; fixes the issue.

lowp, mediump and highp correspond to different values on different hardware and only have an effect on OpenGL ES platforms. Desktop platforms tap into a full implementation of OpenGL or Direct X (as opposed to OpenGL ES), hence, on desktop machines these qualifiers all correspond to the same values. Mobile WebGL typically taps into OpenGL ES, hence on mobile these qualifiers correspond to different values.

In this example lowp and mediump cause glitches on Android and need to replaced with highp.

Generally, if performance is important, using the lowest possible precision is recommended to reduce shader execution time. WebGLRenderingContext.getShaderPrecisionFormat() returns the precision for the shader data types, for vertex and fragment shaders, respectively (MDN). To use the lowest possible precision, the shaders used can be prefixed with the required precision qualifier, based on WebGLRenderingContext.getShaderPrecisionFormat().

E.g.

Since my issue revolved only on not being able to install properly because of some iOS dependencies, I was able to work my way around it by temporarily removing the platform by running this:

If you double-click on your config.xml file, it should open as a tabbed form page in Visual Studio 2017. Under the "Toolset" tab, you have a choice between Cordova 6.3.1 and your global cordova version. Try again to install Cordova 7.0.1 globally. Use Windows Powershell running as Administrator.

You can solve your problem with alpha testing. Use a pattern like the following in your fragment shader:

Ok, I'm a moron. The problem wasn't in the implementation of the renderer, but in the shader. Looking inside the HDRGamma.frag shader ( the shader that the HDR Pass uses), in Shader/Source directory:

Usually it helps to read the documentation.

matplotlib.pyplot.imshow(X, .... )

X : array_like, shape (n, m) or (n, m, 3) or (n, m, 4)

Display the image in X to current axes. X may be an array or a PIL image. If X is an array, it can have the following shapes and types:

MxN – values to be mapped (float or int)
MxNx3 – RGB (float or uint8)
MxNx4 – RGBA (float or uint8)
The value for each component of MxNx3 and MxNx4 float arrays should be in the range 0.0 to 1.0. MxN arrays are mapped to colors based on the norm (mapping scalar to scalar) and the cmap (mapping the normed scalar to a color).

Your array is a float array, but not in the range between 0 and 1. Hence the behaviour of imshow is undefined.

You may normalize to the range between 0 and 1 using normal math operations or, potentially more easily using plt.Normalize, in case you want a linear mapping.

Try defining the minification and magnification parameters for the texture object. eg: gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_MAG_FILTER, gl.LINEAR); gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_MIN_FILTER, gl.LINEAR);

Use the appropriate value for min and mag filter, based on your project requirement.
