aframe - Why is my screen blank in A-Frame? -

-

i opened a-frame scene both using hello world codepen , boilerplate, blank white screen in chrome.

i found solution here.it works me.

details below:

chrome

first, enable hardware acceleration:

go chrome://settings click + show advanced settings button in system section, ensure use hardware acceleration when available checkbox checked (you'll need relaunch chrome changes take effect) enable webgl:

go chrome://flags ensure disable webgl not activated (you'll need relaunch chrome changes take effect) inspect status of webgl:

go chrome://gpu inspect webgl item in graphics feature status list. status 1 of following: hardware accelerated — webgl enabled , hardware-accelerated (running on graphics card). software only, hardware acceleration unavailable — webgl enabled, running in software. see here more info: "for software rendering of webgl, chrome uses swiftshader, software gl rasterizer." unavailable — webgl not available in hardware or software. if status not "hardware accelerated", problems detected list (below the graphics feature status list) may explain why hardware acceleration unavailable.

if graphics card/drivers blacklisted, can override blacklist. warning: not recommended! (see blacklists note below). override blacklist:

go chrome://flags activate override software rendering list setting (you'll need relaunch chrome changes take effect) more information, see: chrome help: webgl , 3d graphics.

firefox

first, enable webgl:

go about:config search webgl.disabled ensure value false (any changes take effect without relaunching firefox) inspect status of webgl:

go about:support inspect webgl renderer row in graphics table: if status contains graphics card manufacturer, model , driver (eg: "nvidia corporation -- nvidia geforce gt 650m opengl engine"), webgl enabled. if status "blocked graphics card because of unresolved driver issues" or "blocked graphics driver version", graphics card/driver blacklisted. if graphics card/drivers blacklisted, can override blacklist. warning: not recommended! (see blacklists note below). override blacklist:

go about:config search webgl.force-enabled set true (like chrome, firefox has use hardware acceleration when available checkbox, in preferences > advanced > general > browsing. however, unlike chrome, firefox not require checkbox checked webgl work.)

safari

go safari's preferences select advanced tab ensure show develop menu in menu bar checkbox checked in safari's develop menu, ensure enable webgl checked
