o3d纹理和透明度

Question

我在盖乐瑞工作的o3d(抄袭版)，我需要使照片透明。照片在hud上。下面是一些代码：

g_canvasInfoPict = o3djs.canvas.create(g_pack, g_hudRoot, g_hudViewInfo);

alphaParam = g_canvasInfoPict.transparentState_.getStateParam("o3d.AlphaReference");
alphaParam.value = 0.5;

alphaParam = g_canvasInfoPict.transparentState_.getStateParam("o3d.BlendAlphaEquation");
alphaParam.value = g_o3d.State.BLEND_SUBTRACT;

alphaParam = g_canvasInfoPict.transparentState_.getStateParam("o3d.SourceBlendFunction");
alphaParam.value = g_o3d.State.BLENDFUNC_ONE;

paramOne = g_canvasInfoPict.transparentState_.getStateParam("o3d.DestinationBlendFunction");
paramOne.value = g_o3d.State.BLENDFUNC_DESTINATION_ALPHA;//or BLENDFUNC_SOURCE_ALPHA or BLENDFUNC_SOURCE_ALPHA_SATUTRATE or BLENDFUNC_ONE or BLENDFUNC_ZERO

g_fullPictCanvas = g_canvasInfoPict.createXYQuad(paddingX, paddingY, -14, g_fullPictTexture.width, g_fullPictTexture.height, true);

g_fullPictCanvas.canvas.drawBitmap(g_fullPictTexture, 0, g_fullPictTexture.height);
g_fullPictCanvas.updateTexture();

但它不起作用。当设置paramOne.value = BLENDFUNC_ZERO照片显示时(非透明)

paramOne.value = BLENDFUNC_ONE照片不显示(全透明)

那么，如何实现中间结果呢？

考虑到为了支持WebGL-based O3D而弃用了O3D插件，您是否可以选择migrate to the latter

如果是，您可以在discussion group中查询透明度问题(如果在o3d-WebGL下仍然存在)。开发人员反应非常灵敏。
