纹理ExtrudeGeometry

Question

我在THREE.ExtrudeGeometry中绘制画布纹理时遇到问题。 以下图片是我想要的

但它似乎运作不佳。它看起来像一个黑色的场景 这是我的项目场景。纹理对于离开PlaneGeometry很好，但是对于正确的ExtrudeGeometry没有用。

var shape = new THREE.Shape(points);

var extrudeSettings = { 
    size: 1, 
    amount: 8, 
    bevelEnabled: false, 
    material: 0, 
    extrudeMaterial: 1 
}; 

var geometry = new THREE.ExtrudeGeometry(shape, extrudeSettings);

var canvas = document.querySelector('.heatmap-canvas'); 

var texture = new THREE.Texture(canvas); 

texture.needsUpdate = true; 

texture.minFilter = THREE.LinearFilter; 

var material = new THREE.MeshLambertMaterial({ 
    map: texture, 
    color: 0xffffff, 
    transparent: true, 
    opacity: 0.7 
}); 

var mesh = new THREE.Mesh(geometry, material);
