師大柯雷吉歐的計圖筆記-Week14

一、Rasterization

size(600,600,P3D);

background(255);

//glBegin(GL_POLYGON);

beginShape(TRIANGLE);

  //glColor3f(r,g,b);

  //glVertex3f(x,y,z);

  stroke(255,0,0);vertex(300,100);

  stroke(255,255,0);vertex(500,500);

  stroke(0,0,255);vertex(100,500);

//glEnd();

endShape();

stroke：畫出一個空心，邊有色彩的三角形

size(600,600,P3D);

background(255);

//glBegin(GL_POLYGON);

beginShape(TRIANGLE);

  //glColor3f(r,g,b);

  //glVertex3f(x,y,z);

  fill(255,0,0);vertex(300,100);

  fill(255,255,0);vertex(500,500);

  fill(0,0,255);vertex(100,500);

//glEnd();

endShape();

fill：畫出實心有色彩的三角形
