javascript - How to console.log in webgl shaders? -

-

i'm trying understand how simulate console.log in webgl shaders written in glsl. it's easy error messages can't how print custom messages.

basically want print stuff in browser's console:

<script id="shader-fs1" type="x-shader/x-fragment">   void main(void)    {      //console.log doesn't work here since it's glsl not javascript     gl_fragcolor = vec4(0.0, 0.0, 0.0, 1.0);    }  </script>

any suggestions?

not sure if possible, may want check out the webgl inspector library debugging purposes.

i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
