[]有关于显存值的设置方法是在官网哪里？

var nMem = conchConfig.getTotalMem();

if (nMem <= 524288) {

    conchConfig.atlasNum = 10;

    conchConfig.maxTextureMemSize = 84 * 1024 * 1024;//图集内存上限

}

else if (nMem > 524288 && nMem <= 1048576) {

    conchConfig.atlasNum = 16;

    conchConfig.maxTextureMemSize = 84 * 1024 * 1024;//图集内存上限

}

else if (nMem > 1048576) {

    conchConfig.atlasNum = 20;

    conchConfig.maxTextureMemSize = 128 * 1024 * 1024;//图集内存上限

}
