4章マテリアル
マテリアルについてはこれまでの章でも簡単に触れました。マテリアルはTHREE.Geometryと組み合わせてTHREE.Meshを構成するものであることはすでに理解できていることでしょう。マテリアルは形状の外側がどのように見えるかを定義するオブジェクトの皮のようなものです。例えばマテリアルは物体が金属のような質感か、透明か、ワイヤーフレームとして描写されるかを指定します。そのマテリアルを使用して作成したTHREE.Meshオブジェクトはシーンに追加してThree.jsで描画することができます。これまでマテリアルについてあまり詳細には説明しませんでした。この章ではThree.jsが提供しているすべてのマテリアルについて詳細に説明し、それらのマテリアルを使用して見た目のよい3Dオブジェクトを作る方法を学びます。この章では、表4-1に挙げたマテリアルについて説明します。
表4-1 マテリアル一覧
| マテリアル | 説明 |
|---|---|
MeshBasicMaterial | ジオメトリに単純な色を設定するか、ワイヤーフレームで表示することができる基本的なマテリアル |
MeshDepthMaterial | カメラからの距離を使用してメッシュの色を決定するマテリアル |
MeshNormalMaterial | 面の色をその法線ベクトルに従って決定する簡単なマテリアル |
MultiMaterial | ジオメトリのそれぞれの面に独自のマテリアルを設定できるマテリアル |
MeshLambertMaterial | ライティングを考慮し、光を鈍く反射する光沢のあまりないオブジェクトの作成に利用するマテリアル |
MeshPhongMaterial | MeshLambertMaterialと同様にライティングを考慮するが、光沢のあるオブジェクトの作成に利用するマテリアル ... |
