I use camera-unproject to do coordinate mapping, but the obtained coordinates are obviously wrong.
code:
const regl = this.$el
const handleMouseDown = (e) => {
const x = 1 - (e.offsetX / regl.clientWidth) * 2
const y = (e.offsetY / regl.clientHeight) * 2 - 1
const point = vec3.fromValues(x, y, 0.5)
const { projection, view, viewport } = this.camera
const combinedProjView = mat4.multiply([], projection, view)
const invProjView = mat4.invert([], combinedProjView)
const result = unproject([], point, viewport, invProjView)
console.log('convasSize: ', [regl.clientWidth, regl.clientHeight])
console.log('viewport: ', viewport)
console.log('clickPoint: ', [x, y])
console.log('unproject result:', result)
}
this.$el.addEventListener('mousedown', handleMouseDown.bind(this))

Could it be that I did something wrong?
