处理:如何使Box()在3D模式下显示固体(非透明)
我正在尝试在处理中创建3D框的层。我希望它们看起来坚固,以便您看不到其他盒子后面的框,但是它们显示的方式使它们看起来透明。您可以看到其他盒子后面的盒子。我如何使它们显得坚固?
// number of boxes
int numBox = 300;
// width of each box
int boxWidth = 30;
// number of boxes per row
float numPerRow;
void setup() {
size(800, 800, P3D);
pixelDensity(1);
colorMode(HSB, 360, 100, 100, 100);
background(40, 6, 85);
stroke(216, 0, 55);
smooth(4);
fill(0, 0, 90, 100);
numPerRow = width / boxWidth;
}
void draw() {
background(40, 6, 85);
translate((boxWidth / 2), 100);
rotateX(-PI/6);
rotateY(PI/8);
for (int i = 0; i < numBox; i++) {
drawBox(i);
if (i == numBox - 1) {
noLoop();
}
}
}
void drawBox(int i) {
if ((i % 2) == 0) {
pushMatrix();
translate(((boxWidth / 2) * i) % width, 20 * floor(i / (2 * numPerRow)));
translate(0, -((i % 30) / 2));
box(boxWidth, i % 30, boxWidth);
popMatrix();
};
}
盒子的显示方式的特写:
I'm trying to create layers of 3d boxes in Processing. I want them to appear solid, so that you can't see the boxes "behind" other boxes, but the way they're displaying makes them seem transparent; you can see the stroke of boxes behind other boxes. How do I make them appear solid?
// number of boxes
int numBox = 300;
// width of each box
int boxWidth = 30;
// number of boxes per row
float numPerRow;
void setup() {
size(800, 800, P3D);
pixelDensity(1);
colorMode(HSB, 360, 100, 100, 100);
background(40, 6, 85);
stroke(216, 0, 55);
smooth(4);
fill(0, 0, 90, 100);
numPerRow = width / boxWidth;
}
void draw() {
background(40, 6, 85);
translate((boxWidth / 2), 100);
rotateX(-PI/6);
rotateY(PI/8);
for (int i = 0; i < numBox; i++) {
drawBox(i);
if (i == numBox - 1) {
noLoop();
}
}
}
void drawBox(int i) {
if ((i % 2) == 0) {
pushMatrix();
translate(((boxWidth / 2) * i) % width, 20 * floor(i / (2 * numPerRow)));
translate(0, -((i % 30) / 2));
box(boxWidth, i % 30, boxWidth);
popMatrix();
};
}

问题在于,这些盒子是相交的,这些相交框的笔触使外观“ see taby”。
我注意到您正在使用X和Y翻译,但不使用Z。
如果您不打算增加x,y间距避免交叉点,则可以轻松地在z轴上偏移行,以便彼此前面出现一排盒子。
这是您的代码的一个稍微修改的版本,说明了此想法:(
单击并拖动以旋转并观察Z偏移量。
随意使Z作为您的兴趣,您需要它。
构图和颜色不错!
(框架(窗口大小)可以使用一些迭代/调整,但我猜这是WIP))

The issue is that the boxes are intersecting and the strokes of these intersecting boxes are what give the appearance of "see through".
I'm noticing you are using x and y translation, but not z.
If you don't plan to increase x, y spacing to avoid intersections, you can easily offset rows on the z axis so rows of boxes appear in front of each other.
Here's a slightly modified version of your code illustrating this idea:
(Click and drag to rotate and observe the z offset.
Feel free to make z as interestersting as you need it it.
Nice composition and colours!
(framing (window size) could use some iteration/tweaking, but I'm guessing this is WIP))
