弯曲后的平面宽度(使用 pv3d、as3dmod)
我遇到了一个大问题。我已经被困在那里两个星期了。 看起来很简单。
我正在创建一个平面,并将纹理映射到它。 之后,我使用 as3dmod 中的弯曲修改器弯曲它。
当然,经过弯曲处理后,平面变小了。
我尝试计算第一个和最后一个顶点。
var sizeAfterBending:Number = (-1 * plane.geometry.vertices[0].x) + (plane.geometry.vertices[plane.geometry.vertices.length-1].x);
我计算 -1 因为第一个顶点始终为负。
结果是,如果平面是 400*533,则工作正常。 但对于 640*480 的平面来说,情况并非如此。
我缺少一些东西。这真的让我发疯。
有人有什么想法吗?
提前致谢。
干杯,丹先生
I got a huge problem. I'm stuck there for two weeks now.
It's seems pretty simple.
I'm creating a plane, mapping a texture to it.
After that I bend it, using the bend modifier from as3dmod.
Of course the plane got smaller after the bending process.
I've tried to calculate the first and last vertices.
var sizeAfterBending:Number = (-1 * plane.geometry.vertices[0].x) + (plane.geometry.vertices[plane.geometry.vertices.length-1].x);
I calculate -1 cause the first vertex is always negative.
The result of that is, if the plane is 400*533 it working fine.
But with a plane of let's say 640*480 it's not.
I'm missing something. It's really driving me crazy.
Does anybody has any idea?
Thanks in advance.
Cheers, MisterDan

JFY,我解决了。
我试图在渲染完成之前访问此信息。
当然,这是行不通的;)
干杯,丹先生
JFY, I solved it.
I was trying to access this information before the rendering was finish.
Of course that's not gonna work ;)
