我正在使用OpenGL并使用GLPaint的示例.我创建了一个应用程序,当用户触摸图像时,它会在图像(纹理)上应用旋转.我有一个问题,我需要保存第一次触摸,然后应用下一阶段,等等.但是在下一次触摸时,先前应用的效果将被删除.
我曾尝试使用深度缓冲区和帧缓冲区,但未能获得所需的结果.我附上了我的所有代码和着色器

#import <QuartzCore/QuartzCore.h>
#import <OpenGLES/EAGLDrawable.h>
#import <GLKit/GLKit.h>

#import "PaintingView.h"

enum {
    ATTRIB_VERTEX,
    NUM_ATTRIBS
};

@interface PaintingView()
{
    // The pixel dimensions of the backbuffer
    GLint backingWidth;
    GLint backingHeight;

    EAGLContext *context;

    // OpenGL names for the renderbuffer and framebuffers used to render to this view
    GLuint viewRenderbuffer, viewFramebuffer, texture;

    // OpenGL name for the depth buffer that is attached to viewFramebuffer, if it exists (0 if it does not exist)
    GLuint depthRenderbuffer;


    Boolean needsErase;

    // Shader objects
//    GLuint vertexShader; …

我在MySQL数据库表中使用JSON列类型。当我尝试在表列中保存JSON值时，JSON数组会自动重新排序（随机播放）

我有以下JSON：

{"TIMER_HEADER": [{"XX!TIMERHDR": "XXTIMERHDR", "VER": " 7", "REL": " 0", "COMPANYNAME": "XXX", "IMPORTEDBEFORE": "N", "FROMTIMER": "N", "COMPANYCREATETIME": "12423426"}, {"XX!HDR": "XXHDR", "PROD": "Qics for Wnows", "VER": "Version 6.0", "REL": "Release R", "IIFVER": "1", "DATE": "2018-01-20", "TIME": "1516520267",   "ACCNTNT": "N", "ACCNTNTSPLITTIME": "0"}], "COLUMN_HEADER": ["!TIMEACT", "DATE", "JOB", "EMP", "ITEM", "PITEM", "DURATION", "PROJ", "NOTE", "BILLINGSTATUS"]}

保存在MySql表的JSON列中后，将变为：

{"TIMER_HEADER": [{"REL": " 0", "VER": " 7", "FROMTIMER": "N", "COMPANYNAME": "XXX", "XX!TIMERHDR": "XXTIMERHDR", "IMPORTEDBEFORE": "N", "COMPANYCREATETIME": "12423426"}, {"REL": "Release R", "VER": "Version 6.0", "DATE": "2018-01-20", "PROD": "Qics …

我尝试在单击按钮时绘制多边形并从另一个按钮删除多边形，第一次工作正常，但删除后我无法绘制另一个多边形。请指导我。这是代码片段：

var polyOptions = {
        strokeWeight: 0,
        fillOpacity: 0.45,
        editable: true,
        fillColor: '#FF1493'
    };  
var selectedShape;

var drawingManager = new google.maps.drawing.DrawingManager({
        drawingMode: google.maps.drawing.OverlayType.POLYGON,
        drawingControl: false,
        markerOptions: {
            draggable: true
        },
        polygonOptions: polyOptions
  });

$('#enablePolygon').click(function(){
        drawingManager.setMap(map);
    });

$('#resetPolygon').click(function(){
        if (selectedShape) {
            selectedShape.setMap(null);
        }
        drawingManager.setMap(null);
        $('#showonPolygon').hide();
        $('#resetPolygon').hide();
    });

function clearSelection() {
        if (selectedShape) {
          selectedShape.setEditable(false);
          selectedShape = null;
        }
    }


    function setSelection(shape) {
        clearSelection();
        selectedShape = shape;
        shape.setEditable(true);
    }

google.maps.event.addListener(drawingManager, 'overlaycomplete', function(e) {
    all_overlays.push(e);
    if (e.type != google.maps.drawing.OverlayType.MARKER) {
      // Switch back …

如何获得phtml文件中具有相同区域设置的所有Magento商店的列表

当我将鼠标悬停在产品视图页面上的任何色板上时，会出现错误：
Uncaught ReferenceError: PointerManager is not defined
我使用了magento 1.9.1，并使用默认的内置颜色和尺寸色板功能创建了可配置产品。将鼠标悬停时会显示错误，但是单击任何一个色板均能正常工作。
悬停的唯一问题。
任何人请帮忙。
谢谢。
