GeForce4 Tiに関する質問があります。
誰かGL_DOT_PRODUCT_AFFINE_DEPTH_REPLACE_NVが何をするか分かりませんか？
この新しいトークンは、GL_NV_texture_shader3のOpenGL拡張(GeForce4 Tiシリーズでのみ利用可能)
の中で定義されているみたいです。
トムのハードウェアにおいて最近の調査の中で言及された「Ｚ補正バンプ・マッピング」
は有利な面と、不利な面の両面がありますか？

Vmag.オンラインのムービークリップを見たことがありますか？
TidepoolデモはＺ補正バンプ・マッピングの効果について説明します。
外部ﾘﾝｸ[html]:www.vwalker.com

実際のジオメトリは置き換えずに、
水面の深度値が表面の高さによってピクセル毎に置換されているように見えます。
私はデモがAFFINE_DEPTH_REPLACEオペレーションか何かを使用していると思います。
みんな「Ｚ補正バンプ・マッピング」の意味を知っています？

>>420、いぇー、私もそう思う。:)
どうも。

Hey 327, you made a great job for us!
(though there seem to be some minor mistranslations...)
Anyway, thanks a lot for your help.

Hi 327, I'm afraid you have mistranslated the following sentences.

>>418 (last sentence)
これは、Tom's Hardwareでの最近のレビューで言及されていた
「Ｚ補正バンプマッピング」と関係があるのでしょうか？

>>420
うーむ、390の言ったとおりフィルタとしてうまく機能しているようだな。

>>421 (third paragraph)
「Ｚ補正バンプマッピング」が一体何を意味しているのか、
誰かわかる人はいませんか？

A certain Japanese console has a unusual need for its clipping
matrix, it needs -|w| < z < +|w| rather then the usual 0 < z < w.

This means any text book clipping matrix, needs modifing
for GS chip what we call FUCH-KUTARAGI-CHIP.

The best reference IMHO for clipping and perspective transforms is
Jim Blin`s Trip down the Graphics Pipeline which describes the
perspective system in details, and it also explains how to create
your own clipping space.

bye.

I'm having a hard problem in transforming a direction vector from
one coordinate space to the another.
I need to transform the direction of the ray from world space
to the object space so I can do an intersection on the triangles
in a mesh.

Thanks for any help

438(2): 02/02/10 06:38 ID:??? AAS

I think you did a very great job but it seems your
translation into the Japanese is calling some suck guys like as 436.
I highly recommend to stop your translating,sorry.

OpenGL, the most popular graphics library in the world, requires that z value in
homogeneous clipping space be within the range between -w and w, as is the case
with your platform. Historically, I believe, this type of projection matrices
rather than DirectX-style projection matrices (0 < z < w) has been widly used.

>>437
You can use the upper-left 3x3 matrix of your transform matrix (from world space
to object space) to transform a direction vector into object space if and only if
the 3x3 matrix is orthonormal, which means the 3x3 matrix represents pure rotation
without any scaling or shearing. Otherwise (if the 3x3 matrix is not orthonormal),
you need to use the inverse transpose of the upper-left 3x3 matrix instead.

>>438
I agree. No Japanese translation is needed for us.
327, we hope you meet our request. Thanks in advance.

441: 440 02/02/10 09:01 ID:??? AAS
Sorry there are typos at the end of first paragraph.
wrong: has been widly used.
correct: have been widely used.

442: 440 02/02/10 09:15 ID:??? AAS
Oops, "has" is correct since the subject of that sentence is "the type"
which is a singular noun. I'm so sorry to have interrupted our discussion.

일반적인 확산 광원을 계산 (본 예제에서는 단방향 광원) 하며, 결과를
확산 반복 색에 넣는 대신 단순한 밴딩 광도 질감의 질감 좌표로 조명
값을 사용합니다. 확산 반복기에 로드된 원하는 재질 색을 갖는 질감을
조정함으로써 채색이 이루어집니다. 다음 Vertex Shader를 참고하십시오.

The clipping topics is one of the most hardest things and required
high skills more than it looks and these discussions might never end.

Is there a place where I can find standrd constraints values
for joints of a human mesh? (saying a list of euler limit angles as used in using UK)
Apparently most of the time they come from an converting proccess but
I would like this to be a little more automatic...well you know if can do,
it sounds reasonable because I'm going to deal only with human bones.

>the 3x3 matrix is orthonormal, which means the 3x3 matrix represents pure rotation
>without any scaling or shearing.

umm...well yes i can undestand the 3x3 matrix can show rotation but
at the same time , it also represent scaling isn't it?

456: 440 02/02/10 16:11 ID:??? AAS
>>455
What I meant is that a "orthonormal" 3x3 matrix represents pure rotation.
If a 3x3 matrix contains scaling or shearing, that matrix is NOT orthonormal.
In this case, you must calculate the inverse of the transpose of the 3x3 matrix,
instead of just using the original matrix, in order to transform "normal" vectors.

However, you said in your previous post (I assume 437 = 455) that you wanted to
transform "direction" vectors. Unlike normals, direction vectors can be transformed
simply by using the upper-left 3x3 submatrix of the original 4x4 transform matrix.
I'm very sorry to have mixed up "direction" with "normal."
